Ashish Singhi commented on HBASE-14938:
---------------------------------------
I am planning to add a new configuration
{{hbase.replication.max.znodes.per.request}} which will control the number of
znodes we send for create/delete to ZK in a single request default being 5000.
For now we do not have any control on the number of znodes we can request from
ZK in one request. There is a open jira in ZK(ZOOKEEPER-2260) and work is in
progress, once that is complete we can control this part also, I will just add
a TODO for this.
Any concern with above approach or do you have any other thoughts ?

> In ZK the maximum allowable size of the data array is 1 MB. Until we have
> fixed HBASE-10295 we need to handle this.
> Approach to this problem will be discussed in the comments section.
> Note: We have done internal testing with more than 3k nodes in ZK yet to be
> replicated.
