Inder SIngh commented on HDFS-693:
----------------------------------

Folks,

What's the recommendation here. Does increasing the timeout resolve this? Does it have any
other side effects.We are hitting the same on medium size cluster ~60 nodes.

 Also, I could see the output of netstate -a | grep 50075 has many TIME_WAIT status when this
