Hello All,
I am using HBase-0.92.0 and Hadoop-0.23.0 . When attempting to create a
table with snappy compression it gets stuck in the PENDING_OPEN state with
the following message repeated in the region server's log file:
2012-02-28 21:08:18,010 INFO

I tried setting HBASE_LIBRARY_PATH ( and HBASE_CLASSPATH just in case ) to
point to the directory containing libsnappy but I am still getting this
error
What else can I do to fix / diagnose this problem?
Thanks!
