Paul Ayers updated CASSANDRA-17503:
-----------------------------------
Resolution: Duplicate
Status: Resolved (was: Open)
> Request to port the DSE rebuild options to Cassandra
> ----------------------------------------------------
>
> Key: CASSANDRA-17503
> URL: https://issues.apache.org/jira/browse/CASSANDRA-17503
> Project: Cassandra
> Issue Type: New Feature
> Reporter: Paul Ayers
> Priority: High
> Fix For: 4.x
>
>
> Testing rebuild in C* 4.0.1, I ran into a scenario where 'nodetool rebuild'
> was ran without any options in a new DC and the system.available_ranges_v2
> table was populated such that every subsequent run of 'nodetool rebuild
> <sourceDC>' streamed no data.
> The problem was that the first run looked at only the new DC so no data was
> streamed, then the next run that provided the correct source DC still
> resulted in no streamed data.
> Once the system.available_ranges_v2 table was truncated, rebuild worked as
> expected.
> The request here is to include the same code that allows the following
> options to be used in DSE so one could easily resolve this by using '-m
> reset' in a similar scenario:
> -m, --mode mode
> * normal - conventional behavior, streams only ranges that are not already
> locally available
> * refetch - resets locally available ranges, streams all ranges but leaves
> current data untouched
> * reset - resets the locally available ranges, removes all locally present
> data (like a TRUNCATE), streams all ranges
> * reset-no-snapshot - (like reset) resets the locally available ranges,
> removes all locally present data (like a TRUNCATE), streams all ranges but
> prevents a snapshot even if auto_snapshot is enabled
> Protecting against updating the available_ranges table if a local DC was
> chosen might also be a good idea.
