--------------------------------------
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.
