Sahil Aggarwal commented on HBASE-20351:
----------------------------------------
Can you please help me reproduce. I tried on branch-2
```
Use "help" to get list of supported commands.
Use "exit" to quit this interactive shell.
Version 2.1.0-SNAPSHOT, r039bc73571d2cc89378749573dfeec74c247b0b9, Thu Apr 5

couldn't see such logs, even tried turning everything to DEBUG mode in log
config.
