-Re: java.lang.NegativeArraySizeException: -1 in hbase

So. After some internal discussions with Anoop, here is a summary of the
An hbase-0.94.0 jar file was included in the MR job client file. But also,
this MR client file was stored into the Master lib directory. And only in
the master and the RS hosted on the same host. Not in any of the other RS
Removing this file from the client, recompiling HBase 0.94.12-SNAPSHOT and
redeploying everything fixed the issue.
What does it mean.
I think there is something between Hbase 0.94.0 and HBase 0.94.12 which is
not compatible. It's not related to the TableSplit class. This class is
like that since 0.94.5. It's most probably related to a more recent
modification which is breaking the compatibility between HBase 0.94.0 and
last HBase 0.94 branch.
The MR job on my server was running for months without any issue, with this
0.94.0 jar included. Which mean the compatibility has been broken recently.
Something like between 0.94.10 and 0.94.12 (I guess).
Now, even if 0.94.12 is not compatible with HBase version < 0.94.5. Is this
something we want to investigate further? Or 0.94.5 versions are already
too old and if there is some break of the compatibility we can live with
