agent unable to send heartbeat

[Rajat]

I found that on one of the datanode /var/lib/cloudera-scm-agent directory has been deleted by mistake.

It has two files -uuid and response.avro.

uuid i have recreated by adding string as per cloudera-server logs.But response.avro got auto re-created in very small size.

But still that node unable to communicate with Master.

Suggessions pls.

I tested avro file gets recreted with same chksum and should be good.

As per log :

2015-09-25 08:45:51,608 ERROR ParcelUpdateService:com.cloudera.parcel.components.ParcelDownloaderImpl: (5 skipped) Unable to retrieve remote parcel repository manifest

Probably something wrong happened to parcel downloaded on this node .(NOde was good for last 2-3 months)
