----------------------------------------
Summary: Regions stuck in FAILED_OPEN when HDFS blocks are missing
Key: HBASE-17704
URL: https://issues.apache.org/jira/browse/HBASE-17704
Project: HBase
Issue Type: Bug
Components: regionserver
Affects Versions: 1.1.8
Reporter: Mathias Herberts
We recently experienced the loss of a whole rack (6 DNs + RS) in a 120 node
cluster. This lead to the regions which were present on the 6 RS which became
unavailable to be reassigned to live RSs. When attempting to open some of the
reassigned regions, some RS encountered missing blocks and issued "No live
nodes contain current block Block locations" putting the regions in state
FAILED_OPEN.
Once the disappeared DNs went back online, the regions were left in
FAILED_OPEN, needing a restart of all the affected RSs to solve the problem.
