> Key: HBASE-11041
> URL: https://issues.apache.org/jira/browse/HBASE-11041
> Project: HBase
> Issue Type: Bug
> Reporter: Lars Hofhansl
>
> Just found a test failing like this:
> {code}
> Error Message
> HTableDescriptor is read-only
> Stacktrace
> java.lang.UnsupportedOperationException: HTableDescriptor is read-only
> at
> org.apache.hadoop.hbase.client.UnmodifyableHTableDescriptor.addFamily(UnmodifyableHTableDescriptor.java:64)
> at
> org.apache.hadoop.hbase.HBaseTestingUtility.createMultiRegions(HBaseTestingUtility.java:1302)
> at
> org.apache.hadoop.hbase.HBaseTestingUtility.createMultiRegions(HBaseTestingUtility.java:1291)

> org.apache.hadoop.hbase.HBaseTestingUtility.createMultiRegions(HBaseTestingUtility.java:1286)

> org.apache.hadoop.hbase.master.TestDistributedLogSplitting.installTable(TestDistributedLogSplitting.java:485)
> at
> org.apache.hadoop.hbase.master.TestDistributedLogSplitting.testMasterStartsUpWithLogSplittingWork(TestDistributedLogSplitting.java:282)
> {code}
> The code that causes this looks like this:
> {code}
> HTableDescriptor htd = table.getTableDescriptor();
> if(!htd.hasFamily(columnFamily)) {
> HColumnDescriptor hcd = new HColumnDescriptor(columnFamily);
> htd.addFamily(hcd);
> }
> {code}
> But note that table.getTableDescriptor() returns an
> UnmodifyableHTableDescriptor, so the add would *always* fail.
> The specific test that failed was
> TestDistributedLogSplitting.testMasterStartsUpWithLogSplittingWork.
> Looks like the HMaster did not have the last table descriptor state, yet.
