Subject Re: VersionInfoAnnotation Unknown for Hadoop/HBase
Date Mon, 29 Apr 2013 14:54:59 GMT
The output of "java -version" is:

java -version
java version "1.5.0"
gij (GNU libgcj) version 4.4.6 20120305 (Red Hat 4.4.6-4)

Copyright (C) 2007 Free Software Foundation, Inc.

Also, when I run:

"hbase org.apache.hadoop.hbase.util.VersionInfo"

I do get the correct output:
3/04/29 09:50:26 INFO util.VersionInfo: HBase 0.92.1-cdh4.1.2
13/04/29 09:50:26 INFO util.VersionInfo: Subversion
file:///data/1/jenkins/workspace/generic-package-rhel64-6-0/topdir/BUILD/hbase-0.92.1-cdh4.1.2
-r Unknown
13/04/29 09:50:26 INFO util.VersionInfo: Compiled by jenkins on Thu Nov  1
18:01:09 PDT 2012

This is strange and because of this I am unable to run my java client which
errores out as mentioned with the following:
java.lang.RuntimeException: hbase-default.xml file seems to be for and old
version of HBase (0.92.1-cdh4.1.2), this version is Unknown
   at
org.apache.hadoop.hbase.HBaseConfiguration.checkDefaultsVersion(HBaseConfiguration.java:68)

Regards,
Shahab
