-----------------------------------------
Assignee: Jason Brown (was: Yuki Morishita)
Maybe one simple improvement would could make would be to have
LeveledManifest.getCandidatesFor be disk-space aware and stop collecting L0
candidates before output space is exhausted.
> insufficient space for compaction when upgrade compaction strategy from
> SizeTiered to Leveled

> Key: CASSANDRA-4467
> URL: https://issues.apache.org/jira/browse/CASSANDRA-4467
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Affects Versions: 1.0.0
> Environment: Ubuntu,Oracle Java 1.7,Cassandra 1.0.10
> Reporter: Cheng Zhang
> Assignee: Jason Brown
> Priority: Minor
> Fix For: 1.2.1
>
>
> Cassandra has two data directories as follow:
> cassandra-disk0 use about 500G, about 250G free space
> cassandra-disk1 use about 500G, about 250G free space
> The max data file is about 400G. When I upgrade from
> SizeTieredCompactionStrategy to LeveledCompactionStrategy, there is no space
> to do this, for the free space of every data directory is small than the
> largest data file. But the total free space is enough for compaction.
