Dima Spivak updated HBASE-12229:
--------------------------------
Attachment: HBASE-12229_v2.patch
Addressed Matteo's suggestion of putting the waitUntilAllRegionsOnline call in
HBaseTestingUtility#createTable. In this case, that meant adding another
overloaded method and, in the process, refactoring an existing one that took a
byte[] tableName to simply invoke my new TableName tableName variant. Finally,
I did a bit of tidying of SnapshotTestingUtils (clean up stale imports and add
a waitFor around a call to #isTableAvailable).
> NullPointerException in SnapshotTestingUtils

> I tracked down occasional flakiness in TestRestoreSnapshotFromClient to a
> potential NPE in SnapshotTestingUtils#waitForTableToBeOnline. In short, some
> tests in TestRestoreSnapshot... create a table and then invoke
> SnapshotTestingUtils#waitForTableToBeOnline, but this method assumes that
> regions have been assigned by the time it's invoked (which is not always the
> case).
