Hi @EricL ,   My cluster running on VM and it is sandbox and we are not expecting very high I/O throughput.   I created softlink parcel-cache into /opt/cloudera/parcels/parcel-cache as /opt/cloudera/parcels different mountpoint with /opt/cloudera/parcel-cache. I tested the mv statement complete instantaneously and parcel distribution phase completed.  This is just my workaround.    Hope cloudera can fix this issue so thread wait until the unpack and copy complete successfully before reading the parcel or have longer timeout or set it as configurable parameter.   Thank you very much for your help rgds, Rama. ...
