[jira] [Updated] (HBASE-5770) Add a clock skew warning threshold
[ https://issues.apache.org/jira/browse/HBASE-5770?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Ian Varley updated HBASE-5770: -- Attachment: HBASE_5770_v1.patch Patch to add warnings on skew not big enough to warrant killing the RS. Add a clock skew warning threshold -- Key: HBASE-5770 URL: https://issues.apache.org/jira/browse/HBASE-5770 Project: HBase Issue Type: Improvement Components: master, regionserver Reporter: Ian Varley Priority: Minor Attachments: HBASE_5770_v1.patch Original Estimate: 1h Remaining Estimate: 1h There's currently an exception thrown by the master when a region server attempts to start up with clock skew greater than some configured amount (defaulting to 30 seconds). However, it'd be nice to get some warnings logged at a value that isn't severe enough to warrant killing the RS, but still represents significant skew that could affect correctness. Will attach a simple patch to add this as a setting. -- This message is automatically generated by JIRA.

[jira] [Updated] (HBASE-5717) Scanner metrics are only reported if you get to the end of a scanner
[ https://issues.apache.org/jira/browse/HBASE-5717?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Ian Varley updated HBASE-5717: -- Attachment: ClientScanner_HBASE_5717-v3.patch Added additional test cases for running off the end of the available results without closing the scanner, and also doing so with closing the scanner (so, all 3 permutations are covered). Scanner metrics are only reported if you get to the end of a scanner Key: HBASE-5717 URL: https://issues.apache.org/jira/browse/HBASE-5717 Project: HBase Issue Type: Bug Components: client, metrics Reporter: Ian Varley Priority: Minor Attachments: ClientScanner_HBASE_5717-v2.patch, ClientScanner_HBASE_5717-v3.patch, ClientScanner_HBASE_5717.patch Original Estimate: 4h Remaining Estimate: 4h When you turn on Scanner Metrics, the metrics are currently only made available if you run over all records available in the scanner. If you stop iterating before the end, the values are never flushed into the metrics object (in the Scan attribute). Will supply a patch with fix and test. -- This message is automatically generated by JIRA.
