facing issue in running BasicOperations

[Pranay Tonpay]

 tried to run BasicOperatoions class as below -

mvn exec:java -Dexec.mainClass="tachyon.examples.BasicOperations" -Dexec.args="tachyon://localhost:19998 mylocalfile MUST_CACHE"

got an error -
java.lang.IllegalArgumentException: URI must be absolute, unless it's empty.

any comments ?

Hi Pranay, 

What directory are you running your command from? What version of Tachyon?

I can run the BasicOperations example successfully for the master branch of Tachyon using:

java -cp ${TACHYON_HOME}/assembly/target/tachyon-assemblies-0.8.0-SNAPSHOT-jar-with-dependencies.jar:${TACHYON_HOME}/examples/target/tachyon-examples-0.8.0-SNAPSHOT.jar tachyon.examples.BasicOperations tachyon://localhost:19998 mylocalfile STORE

The command above assume that Tachyon jar have been compiled (using mvn install) and that an instance of Tachyon is running on the local host.

 thx Jiri ... i tried on 1.8 and got the below -

pranay@pranay-Latitude-E6540:~/TACHYON_NEW/tachyon$ java -cp /home/pranay/TACHYON_NEW/tachyon/assembly/target/tachyon-assemblies-0.8.0-SNAPSHOT-jar-with-dependencies.jar:${TACHYON_HOME}/examples/target/tachyon-examples-0.8.0-SNAPSHOT.jar tachyon.examples.BasicOperations tachyon://localhost:19998 file STORE
Exception in thread "main" java.lang.IllegalArgumentException: No enum constant tachyon.client.WriteType.STORE

    at tachyon.client.WriteType.valueOf(WriteType.java:23)
    at tachyon.examples.BasicOperations.main(BasicOperations.java:115)

When i checked WriteType.java, it doesnt seerm to have STORE enum at all... So i randomly selected MUST_CACHE -
But i got the below error -

Pranay,

When you say 1.8, do you mean 0.8-SNAPSHOT? The error you are seeing for STORE suggests you have not rebuilt and restarted Tachyon (i.e. you are still running version 0.7.1).

I suggest you try the following:

$ cd  /home/pranay/TACHYON_NEW/tachyon

# verify you are on the latest clean version of master branch

$ ./bin/tachyon-stop.sh

$ mvn clean install 

$ ./bin/tachyon format

$ ./bin/tachyon-start.sh local

At this point you should be able to run:

$ java -cp examples/target/tachyon-examples-0.8.0-SNAPSHOT.jar:assembly/target/tachyon-assemblies-0.8.0-SNAPSHOT-jar-with-dependencies.jar -Dtachyon.logs.dir=logs -Dtachyon.logger.type=USER_LOGGER -Dlog4j.configuration=file:conf/log4j.properties tachyon.examples.BasicOperations tachyon://localhost:19998/ /LICENSE STORE

Note that the path to the LICENSE file needs to be absolute, which is the reason for the other error you are seeing.

Best,

Hi Pranay,

Could you please paste here:

- the full stack you get when you encounter the exception

- output of "./bin/tachyon version"

- output of "git log -n 1"

Thanks.

[Jiří Šimša]

Hi Pranay,

Based on the output from "git log", it looks like you have not updated your Tachyon master branch in a while and you have also made modifications yourself.

Could you use the latest version of the master branch with no modifications? It is hard for me to diagnose the problem if I don't know what code base you are using. Thanks.

Best,
