Subject Re: pio status error
Date Wed, 28 Jun 2017 04:58:41 GMT
Hi,

As per the status log, it seems that hbase hasn't been initialized
properly. Try pio-stop-all, then restart hdfs, hbase. That would be like
stop-dfs.sh and start-dfs.sh (for hdfs) and for hbase, stop-hbase.sh and
start-hbase.sh if they are standalone. These command can be run from the
bin folder of the individual installation.

And then do pio-start-all and pio status. It should work.

Thank you
Vaghawan
