HI everyone,
Is there any situation in which creating a new ZK node with the SEQUENCE
flag should result in a "node exists" error? I'm seeing this happening

In short:
Client 1 updates a znode setting its content to X, then X again, then

Hi all,
We are setting up a small Hadoop 13 node cluster running 1 HDFS
master, 9 region severs for HBase and 3 map reduce nodes, and are just
installing zookeeper to perform the HBase coordination and to manage a
few simple process locks for other tasks we run.
Could someone please advise what k
