How to Syncing the Underlayer Filesystem

[Akash Sethi]

my Underlying FileSystem is /tmp

and tachyon is tachyon://localhost:19998/

AND i tried the command 

./bin/tachyon loadufs tachyon://localhost:19998/ /tmp

then i am getting following errors

java.lang.IllegalArgumentException: URI must be absolute, unless it's empty.

at com.google.common.base.Preconditions.checkArgument(Preconditions.java:92)

at tachyon.client.TachyonFS.validateUri(TachyonFS.java:1073)

at tachyon.client.TachyonFS.mkdirs(TachyonFS.java:852)

at tachyon.client.AbstractTachyonFS.mkdir(AbstractTachyonFS.java:121)

at tachyon.client.UfsUtils.loadUfs(UfsUtils.java:79)

at tachyon.client.UfsUtils.main(UfsUtils.java:222)

Usage: java -cp target/tachyon-0.8.2-jar-with-dependencies.jar tachyon.client.UfsUtils <TachyonPath> <UfsPath> [<Optional ExcludePathPrefix, separated by ;>]

Example: java -cp target/tachyon-0.8.2-jar-with-dependencies.jar tachyon.client.UfsUtils tachyon://127.0.0.1:19998/a hdfs://localhost:9000/b c

Example: java -cp target/tachyon-0.8.2-jar-with-dependencies.jar tachyon.client.UfsUtils tachyon://127.0.0.1:19998/a file:///b c

Example: java -cp target/tachyon-0.8.2-jar-with-dependencies.jar tachyon.client.UfsUtils tachyon://127.0.0.1:19998/a /b c

In the TFS, all files under local FS /b will be registered under /a, except for those with prefix c

Hi,

It looks like you are using Tachyon which is relatively out of date. Would it be possible to use an Alluxio version like Alluxio 1.2?

For your specific issue, you may be able to make it work by changing /tmp to file:///tmp

Hope this helps,

Calvin
