I was able to use Hive successfully a few weeks ago. When I tried again
recently, I ran into issues and suspected that the problems may have been
related to Hive's metastore. For better or worse, I tried to simply delete the
"metastore_db" folder and start fresh. However, the "metastore_db" folder does
not seem to be automatically created I run Hive and I still see the same error
messages that I saw before deleting the "metastore_db" folder.
Just for reference: I'm running hadoop on Mac OS X in psuedo-distributed mode
and the mapreduce jobs seem to complete without any issue. I do not see any
significant error or warning messages in datanode, task tracker, job tracker,
name node, etc. Also, as far as I can tell, Derby is installed and none of the
write permissions should be an issue.
Any help would be greatly appreciated.
Thanks!
