      Description

      Similar with append, lazy persist (memory) file should not support truncate currently. Quote the reason from HDFS-6581 design doc:

      Appends to files created with the LAZY_PERSISTflag will not be allowed in the initial implementation to avoid the complexity of keeping in­memory and on­disk replicas in sync on a given DataNode.
