[jira] [Updated] (HIVE-22140) Metrics: unify codehale metric

[ https://issues.apache.org/jira/browse/HIVE-22140?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Laszlo Bodor updated HIVE-22140:
--------------------------------
Summary: Metrics: unify codehale metric frequency unit between metastore and hiveserver2 (was: Metrics: unify codehale metric frequency unit and default between metastore and hiveserver2)
> Metrics: unify codehale metric frequency unit between metastore and hiveserver2

> Key: HIVE-22140
> URL: https://issues.apache.org/jira/browse/HIVE-22140
> Project: Hive
> Issue Type: Bug
> Components: Metastore
> Reporter: Laszlo Bodor
> Assignee: Laszlo Bodor
> Priority: Major

> Currently, different default value and even different unit are used for json metric file generation frequency (for metastore and hiveserver2), which is confusing, especially in a situation when a metastore config can fall back to a corresponding hive config.
> I think ms would be appropriate for both of them, without even changing the default 1m for metastore (so changing it to 60000ms)
> hive.service.metrics.file.frequency
> Hiveserver2:
> https://github.com/apache/hive/blob/master/common/src/java/org/apache/hadoop/hive/conf/HiveConf.java
> {code:java}
> HIVE_METRICS_JSON_FILE_INTERVAL("hive.service.metrics.file.frequency", "5000ms",
> new TimeValidator(TimeUnit.MILLISECONDS),
> "For metric class org.apache.hadoop.hive.common.metrics.metrics2.JsonFileMetricsReporter, " +
> "the frequency of updating JSON metrics file."),
> {code}
> Metastore:
> https://github.com/apache/hive/blob/master/standalone-metastore/metastore-common/src/main/java/org/apache/hadoop/hive/metastore/conf/MetastoreConf.java
> {code:java}
> METRICS_JSON_FILE_INTERVAL("metastore.metrics.file.frequency",
> "hive.service.metrics.file.frequency", 1, TimeUnit.MINUTES,
> "For json metric reporter, the frequency of updating JSON metrics file."),
> {code}
