this is for searching Impala queries thru cloudera manager UI.
I use following filter to find all the queries running with user ids starting with zs:
user RLIKE '.*zs.*'
I needed to write another filter which is more like NOT RLIKE to find those queries for which user does not start with zk. I tried stuff like below but did not work
user NOT RLIKE '.*zk.*'
user RLIKE !'.*zk.*'
Search documentation already and did not find any thing like this.
