[jira] [Updated] (RATIS-705) GrpcClientProtocolClient#close throws
InterruptedException
[ https://issues.apache.org/jira/browse/RATIS-705?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Tsz-wo Sze updated RATIS-705:
-----------------------------
Component/s: gRPC
> GrpcClientProtocolClient#close throws InterruptedException
> ----------------------------------------------------------
>
> Key: RATIS-705
> URL: https://issues.apache.org/jira/browse/RATIS-705
> Project: Ratis
> Issue Type: Bug
> Components: gRPC
> Reporter: Lokesh Jain
> Assignee: Lokesh Jain
> Priority: Major
>
> GrpcClientProtocolClient#close throws InterruptedException. This happens when GrpcClientProtocolClient#close is called from a TimeoutScheduler thread. GrpcClientProtocolClient#close calls scheduler.close() which interrupts all the timeout scheduler threads including the thread executing the close routine. This leads to InterruptedException when channel.awaitTermination is called.
