2016-09-01 13:11 GMT-03:00 Li, Guangxing <guangxing...@pearson.com>: > Hi, > > I have a cluster running 2.0.9 with 2 data centers. I noticed that > 'nodetool repair -pr keyspace cf' runs very slow (OpsCenter shows that the > node's data size is 39 GB and the largest SSTable size is like 7 GB so the > column family is not huge, SizeTieredCompactionStrategy is used). Repairing > a column family on a single node takes over 5 hours. So I am wondering if I > can use option '-local' and '-pr' together, hoping to get some speed up. > But according to documentation at https://docs.datastax.com/ > en/cassandra/2.0/cassandra/tools/toolsRepair.html '...Do not use -pr with > this option to repair only a local data center...'. Can someone tell me the > reason why we should not use options '-local' and '-pr' together? > > Thanks. > > George >
