EOFException when running bin/tachyon format

[Costantinos Costa]

Hello,

I am getting the following exception when i run 'tachyon format'. Could you please provide me with some solution? 

I tried a lot of things in order to fix it but with no luck. If you see the stacktrace the exception occured when tachyon needs to write on hdfs (Path.getFileSystem).

Please find attached the configuration file.

Thanks,
C.

Solved. The 0.20.2-cdh3u4 hadoop version is different with  0.20.2, r911707 so when i execute the 'mvn -Dhadoop.version=0.20.2-cdh3u4 clean install -DskipTests' in order to compile tachyon i replaced the hadoop-core.jar with the system's one.

Thanks for the update. So to clarify, you were running 0.20.2, r911707
version in your Hadoop cluster?
