Charm needed: HBase

[Mark Mims]

HBase formula

Removing new-charm tag from bugs that don't have an actual new-charm to review.

Mark - OK if I steal this off you? Have something working against the hadoop-ubuntu PPA packages...

[Mark Mims (mark-mims)]

np... thanks!

[James Page (james-page)]

OK - I think that these are ready for review now.

This is a two parter:

1) A single hadoop charm that can deploy all of the hadoop mapreduce and hdfs roles either together or in separate service units

2) A single hbase charm that can deploy all of the hbase roles; it also supports the gateways for thrift, avro and rest but I've not been able to test those yet (working on that).

The only thing I have noticed is a bit of raceyness between the namenode and the jobtracker when deployed together in a single service unit as the jobtracker waits for the namenode to get its stuff in order - it causes tasktrackers which check in early in deployments to give up.

Both charms have a pretty comprehensive README.

Oh - and most of my testing has been on the local provider - I have done some in ec2 (will do some more...) which did flush out one bug with dotdee - files in the .d directory must start with numbers!

[James Page (james-page)]

Hadoop charm tested in ec2 as well - works OK; picked up a couple of bugs so have pushed a new revision to the branch.

[Robert Ayres (robert-ayres)]

Have done some testing in EC2, everything seems to work fine.

Have made a couple of minor changes to the documentation in https://code.launchpad.net/~robert-ayres/charms/precise/hbase/trunk - mention of running HDFS in append mode and other corrections.

One thing I did notice was '/etc/dotdee/root/.ssh/authorized_keys.d' directory is world readable along with the various node keys. Not sure if this was intentional, but thought I'd point this out as the 'authorized_keys' file sourced is private.

[James Page (james-page)]

Robert - merges in your changes - thankyou!
