stack updated HADOOP-2688:
--------------------------
Attachment: emptywritable.patch
Jim, please review this patch. In the name of minimal changes this close to release, I did not change HMaster.run making it stay up whatever the exception.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HStoreFile.java
(getReader): Remove synchronize
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HMaster.java
Refactor all meta scans to use two new utility methods that
add checks for empty cells - the cause of this issue.
(getHRegionInfo, getRowMap): Added utility methods for converting
HbaseMapWritable to map keyed by column and a get of COL_REGIONINFO
that does check for empty cell.
