Hi All,
Tested the following scenario with Bookkeeper-4.1 release: ---------------------------------------------------------- Scenario: Prerequisites -> Say BK1, BK2, BK3 1) Create a ledger with say ensemble=3 quorum=2 and added say 100 entries. 2) After this, BK1 machine is isolated by unplug the network cable of BK1. What I've observed is waiting nearly 10seconds for connection timeout from the failed bookie and only after that bkclient is retrying to the other bookie...I'm thinking this will affect the read entries performance. Also, I could see if the machine is reachable(and just shutdown the bookie server) the timeout is very less and immediately retrynig to the other bookie in the ensemble. Is there any thing I'm missing to configure in netty channels or in bookie server side for the bookie connection timeout? Following is the sample log from the test environment: ------------------------------------------------------ 2012-07-06 22:07:59,734 ERROR hidden.bkjournal.org.apache.bookkeeper.client.PendingReadOp: Bookie handle is not available while reading entry: 18 ledgerId: 3 from bookie: /HOST1:3181 2012-07-06 22:08:10,234 ERROR hidden.bkjournal.org.apache.bookkeeper.proto.PerChannelBookieClient: Could not connect to bookie: /HOST1:3181 2012-07-06 22:08:10,234 ERROR hidden.bkjournal.org.apache.bookkeeper.client.PendingReadOp: Bookie handle is not available while reading entry: 21 ledgerId: 3 from bookie: /HOST1:3181 2012-07-06 22:08:21,234 ERROR hidden.bkjournal.org.apache.bookkeeper.proto.PerChannelBookieClient: Could not connect to bookie: /HOST1:3181 2012-07-06 22:08:21,234 ERROR hidden.bkjournal.org.apache.bookkeeper.client.PendingReadOp: Bookie handle is not available while reading entry: 24 ledgerId: 3 from bookie: /HOST1:3181 2012-07-06 22:08:31,734 ERROR hidden.bkjournal.org.apache.bookkeeper.proto.PerChannelBookieClient: Could not connect to bookie: /HOST1:3181 2012-07-06 22:08:31,734 ERROR hidden.bkjournal.org.apache.bookkeeper.client.PendingReadOp: Bookie handle is not available while reading entry: 27 ledgerId: 3 from bookie: /HOST1:3181 2012-07-06 22:08:42,734 ERROR hidden.bkjournal.org.apache.bookkeeper.proto.PerChannelBookieClient: Could not connect to bookie: /HOST1:3181 2012-07-06 22:08:42,734 ERROR hidden.bkjournal.org.apache.bookkeeper.client.PendingReadOp: Bookie handle is not available while reading entry: 30 ledgerId: 3 from bookie: /HOST1:3181 2012-07-06 22:08:53,234 ERROR hidden.bkjournal.org.apache.bookkeeper.proto.PerChannelBookieClient: Could not connect to bookie: /HOST1:3181 Thanks & Regards Rakesh R
