[jira] [Commented] (HADOOP-9079) LocalDirAllocator throws
ArithmeticException
[ https://issues.apache.org/jira/browse/HADOOP-9079?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13502150#comment-13502150 ]
Eli Collins commented on HADOOP-9079:
-------------------------------------
I assume this happens when the local dirs are out of space? Don't think just checking totalAvailable > 0 fixes this, the following loop doesn't bounds check dir, needs to be re-written with a test.
{code}
long randomPosition = Math.abs(r.nextLong()) % totalAvailable;
int dir = 0;
while (randomPosition > availableOnDisk[dir]) {
randomPosition -= availableOnDisk[dir];
dir++;
}
{code}
