> we make snapshot through "nodetool snapshot -t snapshotname " , when
> snapshotname contains special characters like "/", the make snapshot process
> successfully , but the result
> can be different ,when we check the data file directory or use "nodetool
> listsnapshots".
> here is some case :
> 1. nodetool snapshot -t "p/s"
> the listsnapshot resturns snapshot p for all table but actually the snapshot
> name is "p/s";
> also the data directory is like the format :
> datapath/snapshots/p/s/snapshot-datafile-link
> 2. nodetool snapshot -t "/"
> the listsnapshot resturns "there is not snapshot"; but the make snapshot
> process return successfully and the data directory is like the format :
> datapath/snapshots/snapshot-datafile-link
> the Attachements are the result under our environment.
> so for me , we suggest that the snapshot name should not contains special
> character. just throw exception and told the user not to use special
> character.
