[jira] Updated: (HADOOP-2056) A table with row keys containing
colon fails to split regions
[ https://issues.apache.org/jira/browse/HADOOP-2056?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jim Kellerman updated HADOOP-2056:
----------------------------------
Attachment: patch.txt
Many modifications required because region names (which contain start key) were used as file or directory names. Now the startKey is encoded in an order preserving Base64 dialect.

> I assume it's my dodgy key names that triggered this. Replaced the colons with dots and then this exception wasn't thrown anymore.
