Hi James,
Thanks for your help.
The SYSTEM.SEQUENCE has contained 256 regions in the production cluster, if
modify phoenix.sequence.saltBuckets to the less value, will the region number
reduce after restarting hbase service?
Sorry for my chatter, after all restarting the productive cluster is
Hi David,

even if empty region
Is that true, HBase-committers?
You'll need to delete the SYSTEM.SEQUENCE, make sure to set the
phoenix.sequence.saltBuckets property, and bounce your cluster. Then
the next time you try to establish
Like I said before, no it's not ok to drop system tables. If for some
reason you don't want the sequence table presplit 256 ways, you can
set the phoenix.sequence.saltBuckets to specify how many pre-split
regions you'd like it to have (including setting it to 0).
