I think you can't as in previous version, you might want to look at streams (nodetool netstats) and validation compactions (nodetool compactionstats). I don't enter in the details as this has already been answered a lot of time since 0.X version of Cassandra.
The only new thing I was able to find specific to 2.1 is : sstablemetadata <sstable filenames> As you might know, C*2.1 repair all the sstables just once. This command allows you to know the repair status for a SSTable. Maybe can you build your own progression tool using this. I do not use this version and I am not familiar with C*2.1, I might be wrong. More documentation is available at http://www.datastax.com/documentation/cassandra/2.1/cassandra/operations/ops_repair_nodes_c.html C*heers, Alain 2015-01-22 10:55 GMT+01:00 Di, Jieming <jieming...@emc.com>: > Hi, > > > > I am using incremental repair in Cassandra 2.1.2 right now, I am wondering > if there is any API that I can get the current progress of the current > repair job?
