Subject Compatibility Yarn 2.4 with HDFS 2.0
Date Fri, 06 Jun 2014 08:22:52 GMT
Hi all,

I want to upgrade to Yarn 2.4 only. But when it access Hdfs, IPC Server version is mismached.

HDFS (IPC v7) cant respond to YARN (IPC v9) with below error log:
WARN org.apache.hadoop.ipc.Server: Incorrect header or version mismatch from 127.0.0.1:47957
got version 9 expected version 7

I want to know whether it is possible to do this?

Maybe I can change pom to depend on hdfs 2.0, and use maven shade to make hadoop common(2.4
and 2.0) work together

Any suggestions?

Thanks,
Peng
