Subject [jira] Resolved: (HADOOP-2292) HBaseAdmin.disableTable/enableTable aren't synchronous
Date Tue, 27 Nov 2007 23:12:43 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-2292?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jim Kellerman resolved HADOOP-2292.
-----------------------------------

    Resolution: Won't Fix

This is the intended behavior since the administrative operations can take a long time to
execute, it is very likely  that the rpc would time out.

>                 URL: https://issues.apache.org/jira/browse/HADOOP-2292
>             Project: Hadoop
>          Issue Type: Bug
>          Components: contrib/hbase
>    Affects Versions: 0.15.0

> I'm trying to programmatically add a column family to a table.
> I have code that looks like:
> <code>
> admin.disableTable(table);
> try {
>   admin.addColumn(table, new HColumnDescriptor(columnName));
> } finally {
>   admin.enableTable(table);
> }
> HTable ht = new HTable(config, table);
> <code>
> Two things sometimes go wrong here:
> 1. addColumn fails because the table is not disabled
> 2. new HTable() fails because the table is not enabled
> I suspect that the enableTable/disableTable calls are not synchronous, ie. they return
before they are finished.  I can work around this problem by inserting Thread.sleeps after
the enableTable and disableTable calls.
