--------------------------------
Summary: Deal with byte representations of Longs in writer code
Key: YARN-4025
URL: https://issues.apache.org/jira/browse/YARN-4025
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Vrushali C
Assignee: Vrushali C
Timestamps are being stored as Longs in hbase by the HBaseTimelineWriterImpl
code. There seem to be some places in the code where there are conversions
between Long to byte[] to String for easier argument passing between function
calls. Then these values end up being converted back to byte[] while storing in
hbase.
It would be better to pass around byte[] or the Longs themselves as
applicable.
This may result in some api changes (store function) as well in adding a few
more function calls like getColumnQualifier which accepts a pre-encoded byte
array. It will be in addition to the existing api which accepts a String and
the ColumnHelper to return a byte[] column name instead of a String one.
Filing jira to track these changes.
