[jira] [Updated] (HBASE-3904) HConnection.isTableAvailable returns true even with not all regions available.

["Ita Pai (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HBASE-3904?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ita Pai updated HBASE-3904:
---------------------------

    Attachment: 3904_v6.patch

The calls in the try block don't reliably throw RegionException, so most of the time after several retries, it would silently returns.

Attached is another version that fixed this problem, along with some minor changes to the logic.

TestAdmin passed after applying this patch.

> This function as per the java doc is supposed to return true iff "all the regions in the table are available". But if the table is still being created this function may return inconsistent results (For example, when a table with a large number of split keys is created).
