Xiang Li commented on HBASE-17878:
----------------------------------
[-stack]
We are using HBase 1.2.x with Hadoop 2.7.x. If we can have a fix on HBase
1.2.x, it is good us.
Currently, we have 2 ways to fix/bypass it
1. Very tricky one : declare joda-time as a (direct) dependency of
hbase-server(or whatever needed). It results in that 2 sets of joda-time
classes are in the classpath when runtime, one is from joda-time jar we just
declared, the others is from jruby-complete jar. It could work only because
that joda-time is in front of jruby-complete in the classpath due to
lexicographical order. It is very tricky, as If I remember it correctly, it is
not in the Java Language Specification that the one in the front of the
classpath takes precedence.
2. Move the dir of Hadoop(hadoop-mapreduce) to be in front of hbase lib in
HBase's classpath, which is also very tricky.
Both of them have 2 sets of joda-time classes in the classpath.
Regarding
bq. If hbase2 is your target, then jruby is different now.
I see in master branch, jruby-complete 1.6.8 is still used. Do you mean a JIRA
is working on it?
