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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
