Hive gives problems on my CDH5.7 Quickstart VM recently.   Hive command takes forever to launch shell. It took about 30 min to start the shell session. Even after shell is launched, it doesn't execute commands.   $ hive 2016-08-31 15:48:27,827 WARN [main] mapreduce.TableMapReduceUtil: The hbase-prefix-tree module jar containing PrefixTreeCodec is not present.

CDH 5.7 doesn't launch on my VirtualBox 5.1. It thinks for a very long time on the black screen with white band & text "Centos 6.7", finally it givesbunch of error messages with different ids (I think process id's):   init: prefdm main process (xxxx) terminated with status 1 init: prefdm main process ended, respawing (xxxx is numeric, like 3528, 3538,3558,3568,3588, 3598...
