[jira] [Created] (HDFS-17800) Observer node can return partial blocks for erasure coded files

Adam Binford created HDFS-17800:
-----------------------------------

             Summary: Observer node can return partial blocks for erasure coded files
                 Key: HDFS-17800
                 URL: https://issues.apache.org/jira/browse/HDFS-17800
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs
    Affects Versions: 3.4.1
            Reporter: Adam Binford


Similar to https://issues.apache.org/jira/browse/HDFS-13924, https://issues.apache.org/jira/browse/HDFS-16732, and https://issues.apache.org/jira/browse/HDFS-17768, except for erasure coded files. A single block may not be enough to fulfill an erasure coded read, as you need at least the number of data shards of blocks to read an erasure coded file. The checks need to be updated to factor in erasure coded files.
