HI, i am using explicit shading by creating custom shard key for my application using hbase util mumurhash (added snippet below).
int hash = MurmurHash.getInstance().hash(sharekey.getBytes()); hash = Math.abs(hash); int routingValue = hash % shards; I noticed only 5 out of 8 shards used and 3 shards are empty. Please let me know if you see any issues or suggest any new shard key generation mechanism. Thanks. Regards, Anil
