OPENTSDB has such an error:

ConnectionManager:Unexpected exception from downstream for [ID:0xf85323a8, /10.65. the.:3874=/10.65.. 117:4242]java.io.IOException:Broken pipe at Sun. NiO. Ch. Filedispatcher. Write0 (Native Method) ~[na:1.6. 0_27] at Sun. NiO. Ch. Socketdispatcher. Write(Socketdispatcher. Java: -) ~[na:1.6. 0_27] at Sun. NiO. Ch. Ioutil. Writefromnativebuffer(Ioutil. Java:122)

This usually means that the client has been disconnected and TSDB is trying to send an answer. For example, if you write a remote login data point and have a data with an error (bad label, format error, etc.), then TSD?? B is trying to respond with an error message, but the client is missing. In this case, you will not lose any data because the data points will not be written anyway. If you see this error from an HTTP request, then it should be that the client closed the connection before Tsdb had time to respond.

The problem is: Hbaseclient:lost connection with the. META. Region

It seems that the upgrade was lost when the updated version of Sync.jar this jar package.
Try copying your old version of HBase Sync.jar package to the new folder below.
