Paulo Motta commented on CASSANDRA-11337:
-----------------------------------------

tested locally and worked as expected:

{noformat}
nodetool getsstables --hex-format keyspace1 standard1 3330394c344e35313730
~/.ccm/test/node1/data0/keyspace1/standard1-49f7b910e7d511e5ba4be7733a17ee6e/ma-1-big-Data.db
{noformat}

> Sometimes it's useful to retrieve an sstable from the hex string representation of its
key, for instance, when you get an exception like this and you want to find out which sstable
owns the faulty key:
> {noformat}
> java.lang.AssertionError: row DecoratedKey(2769066505137675224, 00040000002e00000800000153441a3ef000)
received out of order wrt DecoratedKey(2774747040849866654, 00040000019b0000080000015348847eb200)
> {noformat}
> In this case,  {noformat}nodetool getsstables ks cf 00040000002e00000800000153441a3ef000{noformat}
will only work if {{ks.cf}} has a blob primary key.
> It's straightforward to retrieve a {{DecoratedKey}} from the hexstr representation of
the key, so we should add a {{--hex-key}} option to allow for that.
> {noformat}nodetool getsstables ks cf --hex-key 00040000002e00000800000153441a3ef000{noformat}
