Key: HBASE-612
URL: https://issues.apache.org/jira/browse/HBASE-612
Project: Hadoop HBase
Issue Type: Bug
Components: io
Environment: CentOS 5.1 Linux x64_64 / JDK 1.6.0_03-b05
Reporter: Andrew Purtell
Priority: Minor
Attachments: hbase-612-0.2-r652919.patch
HColumnDescriptor's readFields() method is version aware but its write() method
is not.
I found this tracing the cause of a NPE in the Master's IPC server processing a
region open message where the serialized HColumnDescriptor objects were a
version earlier than my latest.
Attached is a patch against trunk which cures the problem.
