Hey Arpit,
Thanks for the reply. I have enabled the debug logs and it was large so was not getting fit here. I have uploaded the same on google drive @https://drive.google.com/open?id=0B5_IMN2gwR1aa2JTTXAyMFVrSEU&authuser=1.
Setup Details:
2 Namenode: 192.168.154.162, 192.168.154.163
2 Datanode: 192.168.154.164, 192.168.154.163
Initial policy:
/data -> HOT
/data/arpan-hdd -> ALL_SSD
Placed a file each on /data and /data/arpan-hdd. Both of them went to their respective tier. Everything fine till this point.
Change the policy of /data/arpan-hdd to HOT.
Run mover on /data/arpan-hdd.
Expected result: All blocks on SSD should move to disk.
Actual Result: nothing happens
