Subject [jira] [Commented] (HBASE-12223) MultiTableInputFormatBase.getSplits is too slow
Date Mon, 13 Oct 2014 22:35:35 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12223?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14170133#comment-14170133

Enis Soztutar commented on HBASE-12223:
---------------------------------------

The following change does not seem right: 
{code}
-    Connection connection = ConnectionFactory.createConnection(context.getConfiguration());
-    Table table = connection.getTable(tSplit.getTable());
+    HTable table =
+        new HTable(context.getConfiguration(), tSplit.getTableName());
{code}
It is changing the new style of API usage into deprecated usage.
