[STORM-876] Blobstore API
Please take a look at the blobstore API. The design docs have been uploaded
earlier under the same JIRA. Currently, the blobstore API also works with
Nimbus-HA. Apart from the unit tests written for blobstore and nimbus leader
election, I have performed few manual tests. Having the PR early looking for
suggestions and any missed failover scenarios while the work continues on other
additional integration tests and better interface. The manual tests that have
been performed are
1. CRUD operations for the blobstore API. Tested for the Local and Hdfs
blobstore operations to work with Nimbus-HA and whether the other nimbodes
mirror the operations performed on master nimbus.
2. Brought up 3 nimbodes and launched a word count topology. Killed the
leader daemon and checked whether other non-leader takes up the leadership and
continues to run.
3. Tested whether topology waits for replication to take place before it is
launched. For hdfs blobstore the blobstore.replication should be set greater
than or equal to topology.min.replication to work effectively.
4. The blobstore with nimbus-ha does not guarantee updates to sync
effectively in the case of failover.
Follow up code to be written.
1. Integration test for blobstore with nimbus-ha
2. Move the sync thread in nimbus to blobstore. Waiting on pacemaker push
back as it uses some of its code and write the callback code for blobstore
