----------------------------------
Summary: DFSInputStream may infinite loop requesting block
locations
Key: HDFS-11379
URL: https://issues.apache.org/jira/browse/HDFS-11379
Project: Hadoop HDFS
Issue Type: Bug
Components: hdfs-client
Affects Versions: 2.7.0
Reporter: Daryn Sharp
Assignee: Daryn Sharp
Priority: Critical
DFSInputStream creation caches file size and initial range of locations. If
the file is truncated (or replaced) and the client attempts to read outside the
initial range, the client goes into a tight infinite looping requesting
locations for the nonexistent range.
