[Hadoop-studio-users] Karmasphere Studio (Community) Compatibility With Hadoop 0.20.203.0?

[Jim Gargani]

Hi,

 

Is Karmasphere Studio (Community) compatible with Apache Hadoop 0.20.203.0?  We have been using Karmasphere Studio just fine with Apache Hadoop 0.20.2 for a while now.

 

All I’m trying to do is browse an HDFS file system which I’ve defined as Hadoop 0.20.2 since there was no option for 0.20.203.0 and I get the following errors:

 

SEVERE com.karmasphere.studio.hadoop.client.hdfs.vfs.HdfsFileSystem error:

java.io.EOFException: Closed connection before call complete; abandoned call Invocation<public abstract long

com.karmasphere.studio.hadoop.client.io.rpc.VersionedProtocol.getProtocolVersion(java.lang.String,long)

throws

Any insight would be most appreciated!

Jim,

We are currently not compatible with Hadoop 0.20.203.0, it is on our roadmap though.
