Subject [jira] Commented: (HIVE-1675) SAXParseException on plan.xml during local mode.
Date Mon, 06 Dec 2010 10:13:23 GMT


Bennie Schut commented on HIVE-1675:

The good news is I'm unable to reproduce this once I "set hive.exec.parallel=false". Perhaps
it's cleaning uo some things during one of the steps while the other steps still need it?
hive.exec.parallel works great for non local stuff for us but the combination of local and
parallel seems like it has some issues. 
I was getting all kinds of different exceptions on local mode like the saxparser but also:

org.apache.hadoop.util.DiskChecker$DiskErrorException: Could not find taskTracker/jobcache/job_local_0001/attempt_local_0001_m_000000_0/output/file.out
in any of the configured local directories
	at org.apache.hadoop.fs.LocalDirAllocator$AllocatorPerContext.getLocalPathToRead(
	at org.apache.hadoop.fs.LocalDirAllocator.getLocalPathToRead(
	at org.apache.hadoop.mapred.MapOutputFile.getOutputFile(
	at org.apache.hadoop.mapred.LocalJobRunner$

and: HIVE_PLAN1fe0a487-2e46-44e4-a557-9b3c9dddac07 (No such file
or directory)
	at Method)
	at org.apache.hadoop.hive.ql.exec.Utilities.getMapRedWork(
	at org.apache.hadoop.mapred.LocalJobRunner$

I only get these issues when enabling parallel and local.
At least an angle to look at.
