Method Detail

parseRanges

public static java.util.Set<Range<Token>> parseRanges(java.lang.String rangesStr,
                                                      IPartitioner partitioner)

parse

public static RepairOption parse(java.util.Map<java.lang.String,java.lang.String> options,
                                 IPartitioner partitioner)

Construct RepairOptions object from given map of Strings.

Available options are:

Repair Options

key	value	default (when key not given)
parallelism	"sequential", "parallel" or "dc_parallel"	"sequential"
primaryRange	"true" if perform repair only on primary range.	false
incremental	"true" if perform incremental repair.	false
trace	"true" if repair is traced.	false
jobThreads	Number of threads to use to run repair job.	1
ranges	Ranges to repair. A range is expressed as <start token>:<end token> and multiple ranges can be given as comma separated ranges(e.g. aaa:bbb,ccc:ddd).
columnFamilies	Specify names of ColumnFamilies to repair. Multiple ColumnFamilies can be given as comma separated values(e.g. cf1,cf2,cf3).
dataCenters	Specify names of data centers who participate in this repair. Multiple data centers can be given as comma separated values(e.g. dc1,dc2,dc3).
hosts	Specify names of hosts who participate in this repair. Multiple hosts can be given as comma separated values(e.g. cass1,cass2).
pullRepair	"true" if the repair should only stream data one way from a remote host to this host. This is only allowed if exactly 2 hosts are specified along with a token range that they share.	false
forceRepair	"true" if the repair should continue, even if one of the replicas involved is down.	false
optimiseStreams	"true" if we should try to optimise the syncing to avoid transfering identical ranges to the same host multiple times	false

Parameters:

options - options to parse

partitioner - partitioner is used to construct token ranges
