Error during rebalance and compaction

1. Install CB Server on 1 node and create bucket:
http://10.6.2.144:8091/pools/default/buckets with param: bucketType=membase&evictionPolicy=valueOnly&threadsNumber=3&ramQuotaMB=2069&proxyPort=11211&authType=sasl&name=default&flushEnabled=1&replicaNumber=1&replicaIndex=1&saslPassword=None
2. Add 5 views to the bucket
3. Change default bucket settings to:
autoCompactionDefined=true&parallelDBAndViewCompaction=false&ramQuotaMB=2069
4. Add data for bucket and check for fragmentation %
5. Run index queries with stale=false
6. Add another node to the cluster and rebalance
7. While the rebalance is going on compaction for view is going on.
