Hi there,
I tried to put my data to HBASE(hbase-0.20.0-alpha) with 3PCs,
one master, two region servers.
It seems ok to put my first 1 million record of data,
but regions crashed while putting my second table's data(3 million)
(org.apache.hadoop.hbase.NotServingRegionException).
I tried to restart zookeeper and hbase, then tried to view its status from
webpage and hbase shell.
It all showed NullPointerException.
Any suggestions?
Thank you.
