[jira] [Resolved] (HBASE-5779) Master goes to infinite loop if

> Key: HBASE-5779
> URL: https://issues.apache.org/jira/browse/HBASE-5779
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.92.1
> Reporter: Shrijeet Paliwal
>
> Steps to reproduce:
> - change permission of /hbase to a user other than one running hbase
> - delete hbase.id if already exists
> - start master, it will try to create cluster ID file in /hbase and fail while doing so with org.apache.hadoop.security.AccessControlException
> From this point it will go to infinite loop.
> Reason: org.apache.hadoop.hbase.util.FSUtils.setClusterId has a wait > 0 and no control over retries when called during master initialization.
> Quoting : checkRootDir in MasterFileSystem
> {noformat}
> // Make sure cluster ID exists
> if (!FSUtils.checkClusterIdExists(fs, rd, c.getInt(
> HConstants.THREAD_WAKE_FREQUENCY, 10 * 1000))) {
> FSUtils.setClusterId(fs, rd, UUID.randomUUID().toString(), c.getInt(
> HConstants.THREAD_WAKE_FREQUENCY, 10 * 1000));
> }
> {noformat}
