Duo Zhang updated HBASE-14969: ------------------------------ Attachment: HBASE-14969-addendum-branch-1.patch Patch for branch-1. On master, we have this {code:title=BaseLoadBalancer.java} // Regions of these tables are put on the master by default. private static final String[] DEFAULT_TABLES_ON_MASTER = new String[] {AccessControlLists.ACL_TABLE_NAME.getNameAsString(), TableName.NAMESPACE_TABLE_NAME.getNameAsString(), TableName.META_TABLE_NAME.getNameAsString()}; {code} So on master we do not have the problem. But I suggest we should also apply the patch for master. [~liyu] Is this patch OK for you?

However, even with > this control on, we are still observing disk utils near 100%, and by analysis > we think this is caused by flush, especially when we increase the setting of > {{hbase.hstore.flusher.count}} > In this JIRA, we propose to add throughput control feature for flush, as a > supplement of HBASE-8329 to better control IO pressure. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
