You can do that through the hbase shell doing a

hbase(main):011:0> truncate 'SYSTEM.MUTEX'

Hi Flavio,

What is your server side Phoenix jar version and client side Phoenix version, note that server side has to have a higher version than client side.

Another note, I got a similar issue the other day. I solved it by truncate system Mutex table. Hope it helps yours too.

Hi to all, 
I've recently updated my Cloudera + Phoenix from CDH 5.9 + 4.7 to CDH 5.11.2 + 4.13 but now I can't connect with Phoenix anymore. When I run phoenix-sqlline.sql I get:

WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

How can I repair my installation? I can't find any log nor anything strange in the SYSTEM.CATALOG HBase table..

Thanks in advance,
