Challengers installing Titan 1.0.0 on Windows

[David Crouch]

Hi,

I downloaded the Zip file and have been having problems installing Titan per the docs. I have tried it on two different computers - a relatively clean Windows 8 machine, and a Windows 7 machine with the same results. Firstly, my Java environment:-

------------------------------------------------------------------------------

java version "1.8.0_25"

Java(TM) SE Runtime Environment (build 1.8.0_25-b18)

Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)

=================================================

I have set the Java_Home environment variable. I first tried to open the Gremlin console:-

-----------------------------------------------------------------------------

D:\titan-1.0.0-hadoop1>bin\gremlin

Error opening zip file or JAR manifest missing : ..\lib\jamm-0.3.0.jar

Error occurred during initialization of VM

agent library failed to init: instrument

================================================

I saw similar problems raised on the web but did not find a solution. The file definitely exists in the "lib" directory. 

I then tried to run the Gremlin server with a default config:-

------------------------------------------------------------------------------

D:\titan-1.0.0-hadoop1>bin\gremlin-server

SLF4J: Class path contains multiple SLF4J bindings.

SLF4J: Found binding in [jar:file:/D:/titan-1.0.0-hadoop1/lib/logback-classic-1.1.2.jar!/org/slf4j/impl/StaticLoggerBinder.class]

================================================

...and running the Gremlin server explicitly specifying the config file (I also tried it by copying the yaml file to the "conf" directory with the same results):-

============================================================

I couldn't run a Gremlin shell to confirm if the Gremlin server is running correctly so I'm not sure. It says it is but I was confused by the errors. I did stop and re-start the Gremlin server because I thought they may have been first time initialization errors but got the same results. 

I saw a titan.sh file specified in the docs but there is no "bat" file equivalent. I recall from Titan 0.3 days having to do a "titan start" but couldn't find that anywhere in the docs. 

 

What am I missing?

Thanks,

Dave

You should try Java 8 update 40 or higher. I believe that is the minimum TP3 level.

Dan has this issue open for better checks against the Java version https://github.com/thinkaurelius/titan/issues/1154

[David Crouch]

Hi Jason,

I have Java 1.8.0_40 running on the 2nd machine (Windows 8) and still received the same errors. I'll download the latest patch and try it again.

Thanks,

Dave 

P.S. How do I change my spelling error in the topic title?   I was thinking of the 49ers-Cardinals game when I typed it up..LOL..

[Effy Teva]

I've add some issues as well.

One of which I couldn't solve yet, is reducing the log level from DEBUG to INFO/WARN.

First, the java parameter "Dlog4j.configuration" in gremlin-server.bat points to an invalid path.

Second, when I point it to a correct path, the log is still always DEBUG, when Threshold=INFO.

Any clues?

Thanks,

Effy

Hi Jason,

Did you manage to resolve this issue?

gremlin-server.bat works for me, but gremlin.bat doesn't.

I'm using Java 1.8.0_51 on Windows 10 (x64)

Thanks,

Effy

Hi,

 

I'm not sure exactly what's going on here.  It might be limited to path issues... it seems plausible that bin\gremlin.bat tries to evaluate ..\lib\jamm-0.3.0.jar from the wrong working directory, and I think I saw a slash direction mismatch somewhere in the thread.  On the other hand, it might be more complicated.

 

If someone has the time and interest to fix and test the shell scripts in Windows, a pull request against titan10 would be welcome.

 

thanks,

Dan

I managed to get gremlin.bat running, but can't get cassandra-embedded running on it. Using the same titan-cassandra-embedded.properties file works well on gremlin-server.bat.

ERROR o.a.c.config.DatabaseDescriptor - Fatal configuration error

org.apache.cassandra.exceptions.ConfigurationException: Expecting URI in variable: [cassandra.config].  Please prefix the file with file:\\\ for local files or file:\\<server>\ for remote files. Aborting. If you are executing this from an external tool, it needs to set Config.setClientMode(true) to avoid loading configuration.

Any clue? I couldn't find any "cassandra.config" setting.

Thanks,

Effy

Inspired by Effy's progress here are the changes to gremlin.bat needed to make it work as documented:-

CHANGE  

    set LIBDIR=..\lib  

TO  

    set LIBDIR=lib

CHANGE

if "%CP%" == "" (

set CP=%LIBDIR%\%1

)else (

set CP=%CP%;%LIBDIR%\%1

)

TO

if "%CP%" == "" (

set CP=%1

)else (

set CP=%CP%;%1

)

In hindsight it appears the script may have been designed to run from the "bin" directory. Per the docs I was trying to run it from the Titan root directory.

Regards,

Dave

That looks like a good start, David. I wonder if just using gremlin.bat straight out of TinkerPop 3.0.1 would work with Titan.

On a quick glance, it looks like the jamm-0.3.0.jar is the only Titan-specific difference (Cassandra-specific even).

You'll want to take a look at the gremlin.bat from TinkerPop3 also to make sure it pulls in any extension jars.
https://github.com/apache/incubator-tinkerpop/blob/master/gremlin-console/src/main/bin/gremlin.bat#L24-L33

Also check out the -Djline.terminal=none in cases the arrow keys don't work for shell history.

I've been trying to conquer Effy's problem of reducing the gremlin server log level as well but with no luck. It seems to ignore the settings as mentioned by Effy (even after correcting the path problem). Any suggestions?

Thanks,

Dave

[Stephen Mallette]

how are you specifying the path to the log4j properties file?

I'm using the default setting on gremlin-server.bat:

java -Dlog4j.configuration=conf/gremlin-server/log4j-server.properties

[Stephen Mallette]

That definitely works off Windows.  Perhaps you should try to specify it as a URL for windows?  absolute pathing? maybe that will help?

Hi Stephen,

Made some tests, and finally managed to get the log4j properties file to load.

I had to write an absolute path, prefixed with "file:\\\\" (such as -Dlog4j.configuration=file:\\\\D:/titan/conf/gremlin-server/log4j-server.properties)

My simple log4j properties file, which I believe shouldn't generate an DEBUG messages is:

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

log4j.rootLogger=WARN, stdout

However, I still receive tons of debug messages (such as: [gremlin-server-worker-1] DEBUG log-aggregator-encoder)

What am I missing...?

Thanks,

Effy

When I add "-Dlog4j.debug", I get the following messages in the gremlin-server.bat console output:

log4j: Using URL [file:////D:/titan/conf/gremlin-server/log4j-server.properties] for automatic log4j configuration.

I've found that you sometimes need to turn off certain loggers more specifically - for example:

https://github.com/apache/incubator-tinkerpop/blob/809da22648067d178b114d9afbdeb5ffbf44ed9e/gremlin-server/conf/log4j-server.properties#L20

Hi Stephen,

I've noticed this line as well when browsing the gremlin server configuration.

However, this is specific for Neo4j.
Do you know which specific configuration is relevant for Titan?

Thanks!

Effy

[Stephen Mallette]

You're going to need the logger name.  I think you can change the log4j pattern to include that:

Hi Stephen,

I've finally managed to overcome this issue.

The logs come from logback.

Adding a logback.xml file in titan root folder, solved this.

Logback.xml file contents:

<configuration>

  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">

    <!-- encoders are assigned the type

         ch.qos.logback.classic.encoder.PatternLayoutEncoder by default -->

    <encoder>

      <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>

    </encoder>

  </appender>

  <root level="info">

    <appender-ref ref="STDOUT" />

  </root>

</configuration>

Perhaps this should be documented somewhere...

Regards,

Effy

[Stephen Mallette]

yeah - there's that weird logback dependency in there.  think that has something to do with cassandra if i remember some stuff dan said about logging. forgot about that until you mentioned it now.  Please create an issue in Titan that references this thread and describes your solution - perhaps the answer is to include the logback.xml file in packaging.  If you have a pull request that would be cool too.

Effy, David,

I've opened up an issue to track this https://github.com/thinkaurelius/titan/issues/1242

Please comment there if there are any other changes to the *.bat files that might be needed.

Thanks!

Jason, thanks for digging into this. I'm sorta glad we're a bit delayed on Titan 1.1 as it would be nice to have this fix in place for it.
