Subject Re: [VOTE] The first hbase-2.0.0-beta-1 Release Candidate is available
Date Sun, 31 Dec 2017 05:48:41 GMT
Hi Stack,

I just tried to give it a try... Wipe out all HDFS content and code, all
HBase content and code, and all ZK. Re-build a brand new cluster with 7
physical worker nodes. I'm able to get HBase start, how-ever I'm not able
to get my regions online.

I'm 99% confident this is because of SNAPPY. I'm fighting to get it working
but it's such a pain! My concern here is I don't see any exception anywhere
on any logs. Nothing on the RS side, nothing on the master side (Except
extract above).

I suspect it's snappy because of this:

But I think my installation is fine:

an in hbase-env.sh:
export JAVA_HOME=/usr/local/jdk1.8.0_151
export HBASE_LIBRARY_PATH=/home/hbase/hbase-2.0.0-beta-1/native-build


So there is 2 things here.
1) Why are the region servers not reporting any error when they are not
able to open a region because of the compression codec not being loaded?
2) Why is HBase not picking up the Snappy codec.

Thanks,

JMS
