Re: Storm cannot run in combination with a recent Hadoop/HBa

We faced this issue couple weeks ago and ended up patching the code ourselves 
since it was such a small change.

We weren't aware of the performance issue with the curator client. We don't see 
anything obvious, so I wonder if that's an edge case of some sort.

Hi,

I'm trying to write some storm bolts and I want them to output the information 
they produce into HBase.
Now the HBase we have running here is based on CDH 4.5.0 which is fully based 
on the zookeeper versions in the 3.4.x range.

The problem I have is that Storm currently still uses zookeeper 3.3.3

The important difference in my case between these two is that 
3.3.x has:  org.apache.zookeeper.server.NIOServerCnxn$Factory
3.4.x has:  org.apache.zookeeper.server.NIOServerCnxnFactory  

As a consequence I'm getting a ClassNotFoundException.

I found that during a short period this problem was fixed but because of a 
performance problem in curator was turned back.

What does it take to get this fixed (i.e. zookeeper goes to a 3.4.x version)?
