Hello Mahesh Reddy, Alexey Serbin, Yuqi Du, Yingchun Lai, Yifan Zhang, Kudu Jenkins,
I'd like you to reexamine a change. Please visit http://gerrit.cloudera.org:8080/20282 to look at the new patch set (#19). Change subject: KUDU-3498 Scanner keeps alive in periodically ...................................................................... KUDU-3498 Scanner keeps alive in periodically Kudu caches the scanner in the tablet server for continuing reading. It will be expired if the idle time is over the defined scanner ttl time. Sometimes the client reads a batch of data, if the data is every large, it takes a long time to handle it. Then the client reads the next batch using the same scanner, the scanner will be expired even if it has sent a keep alive request. This patch adds support for keeping a scanner alive periodically. It uses a timer to send keep alive requests background. So, it will never be expired when the scanner is in using.
