ivakegg opened a new issue, #3346:
URL: https://github.com/apache/accumulo/issues/3346
We we seeing cases where a scan on a remote tserver (possibly for data from
accumulo.root) fails and this results in the local tserver be halted. This
happened on 3 tservers at the same time running a scan on the same remote
tserver. The exception looks something like this:
```
org.apache.accumulo.core.util.threads.ThreadPools$ExecutionError: Critical
scheduled background task failed.

org.apache.accumulo.core.util.threads.ThreadPools.checkTaskfailed(ThreadPools.java.139)

Caused by: java.util.concurrent.ExecutionException:
java.lang.RuntimeException:

```
I do not see any exceptions in the RemoteHost logs that correlate with these
failures. I see the accumulo.audit INFO message "operation: Permitted; user:
<user>; client: <ip>:<port>; action: authenticate" but I do not see any
exceptions or other messages.
