    Description

      Our doc has a statement regarding EC limitations:
      https://hadoop.apache.org/docs/r3.3.0/hadoop-project-dist/hadoop-hdfs/HDFSErasureCoding.html#Limitations

      append() and truncate() on an erasure coded file will throw IOException.

      In fact, HDFS-7663 added the support since Hadoop 3.3.0. The caveat is that it supports "Append to a closed striped file, with NEW_BLOCK flag enabled"
