             Summary: "Partial cell read caused by EOF" ERRORs on replication source during replication
                 Key: HBASE-12419
                 URL: https://issues.apache.org/jira/browse/HBASE-12419
             Project: HBase
          Issue Type: Bug
    Affects Versions: 0.98.7
            Reporter: Andrew Purtell
             Fix For: 2.0.0, 0.98.8, 0.99.2


We are seeing exceptions like these on the replication sources when replication is active:
{noformat}
2014-11-04 01:20:19,738 ERROR [regionserver8120-EventThread.replicationSource,1] codec.BaseDecoder: Partial cell read caused by EOF: java.io.IOException: Premature EOF from inputStream
{noformat}

HBase 0.98.8-SNAPSHOT, Hadoop 2.4.1.

Happens both with and without short circuit reads on the source cluster.

I'm able to reproduce this reliably:
# Set up two clusters. Can be single slave.
# Enable replication in configuration
# Use LoadTestTool -init_only on both clusters
# On source cluster via shell: alter 'cluster_test',{NAME=>'test_cf',REPLICATION_SCOPE=>1}
# On source cluster via shell: add_peer 'remote:port:/hbase'
# On source cluster, LoadTestTool -skip_init -write 1:1024:10 -num_keys 1000000
# Wait for LoadTestTool to complete
# Use the shell to verify 1M rows are in 'cluster_test' on the target cluster.

All 1M rows will replicate without data loss, but I'll see 5-15 instances of "Partial cell read caused by EOF" messages logged from codec.BaseDecoder at ERROR level on the replication source.
