Subject [PredictionIO Error] Running Hbase
Date Sat, 11 Mar 2017 02:28:18 GMT

Yesterday I found the disk is fulled, which lead to Hbase failure:

line 50: echo: write error: No space left on device*
*Java HotSpot(TM) 64-Bit Server VM warning: Insufficient space for shared
memory file:*
*   853*
*Try using the option to select an alternate temp

So I spare a lot of disk spaces, and tried to `pio-stop-all` and
`pio-start-all`. Then `pio status` gave me error:

My guess is that it fails whenever it tried to restart zookeeper.

My & some error in `hbase-crs-master-PredictIO3.log` is also

Thank you!!!!
