Cluster Wide Pauses
-------------------
Key: HBASE-3438
URL: https://issues.apache.org/jira/browse/HBASE-3438
Project: HBase
Issue Type: Bug
Affects Versions: 0.89.20100924
Environment: CentOS 5.5, 10 Nodes, 24GB RAM, 4 1TB Disks, 8GB Heap
Reporter: Wayne
Under heavy write load the entire cluster seems to pause with all nodes pausing
writes/reads for several seconds at a time. This seems to be worse with larger
region sizes. One possible explanation is that a single node gets
caught/paused/stuck during a split and that all other nodes are waiting on that
one node so it looks like a cluster wide pause.
