Subject [jira] [Commented] (HBASE-18444) Add support for specifying custom meta table suffix
Date Fri, 01 Sep 2017 22:35:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18444?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16151249#comment-16151249
] 

Ted Yu commented on HBASE-18444:
--------------------------------

{code}
539	    if(isValidMetaTableSuffix(metaTableSuffix)) {
540	      metaTableName = DEFAULT_META_TABLE_NAME_STR + "_" + metaTableSuffix;
{code}
isValidMetaTableSuffix() gives the impression that metaTableSuffix should be the whole suffix.
But line 540 adds underscore.
Suggest consolidating with variable holding the whole suffix.

Please attach patch for master branch.

> This patch provides user an ability to have a custom meta table suffix.
> In order to share a common rootDir amongst multiple HBase clusters, we need separate
meta table for each cluster.
> With custom meta table suffix, the meta table is named in the form of meta_{suffix} making
it specific to a cluster.
> Users can specify the meta table suffix as part of hbase-site.xml.
