Dave Thompson created HADOOP-8703: ------------------------------------- Summary: distcpV2: turn CRC checking off for 0 byte size Key: HADOOP-8703 URL: https://issues.apache.org/jira/browse/HADOOP-8703 Project: Hadoop Common Issue Type: Bug Affects Versions: 0.23.3 Reporter: Dave Thompson Assignee: Dave Thompson Fix For: 0.23.3
DistcpV2 (hadoop-tools/hadoop-distcp/..) can fail from checksum failure, sometimes when copying a 0 byte file. Root cause of this may have to do with an inconsistent nature of HDFS when creating 0 byte files, however distcp can avoid this issue by not checking CRC when size is zero. This issue was reported as part of HADOOP-8233, though it seems like a better idea to treat this particular aspect on it's own. -- This message is automatically generated by JIRA.
