Apache HBase gets better only when people contribute!
As Apache HBase is an Apache Software Foundation project, see Appendix H, HBase and the Apache Software Foundation for more information about how the ASF functions.
Sign up for the dev-list and the user-list. See the mailing lists page. Posing questions - and helping to answer other people's questions - is encouraged! There are varying levels of experience on both lists so patience and politeness are encouraged (and please stay on topic.)
Check for existing issues in Jira. If it's either a new feature request, enhancement, or a bug, file a ticket.
The following is a guideline on setting Jira issue priorities:
Blocker: Should only be used if the issue WILL cause data loss or cluster instability reliably.
Critical: The issue described can cause data loss or cluster instability in some cases.
Major: Important but not tragic issues, like updates to the client API that will add a lot of much-needed functionality or significant bugs that need to be fixed but that don't cause data loss.
Minor: Useful enhancements and annoying but not damaging bugs.
Trivial: Useful enhancements but generally cosmetic.
