[kudu-CR] KUDU-2914: Rebalance tool support moving replicas from some specific tablet servers
Hello Alexey Serbin, Kudu Jenkins, Andrew Wong, Adar Dembo, I'd like you to reexamine a change. Please visit http://gerrit.cloudera.org:8080/14154 to look at the new patch set (#3). Change subject: KUDU-2914: Rebalance tool support moving replicas from some specific tablet servers .. KUDU-2914: Rebalance tool support moving replicas from some specific tablet servers Aims to support moving replicas from specific tablet servers, this patch re-uses the '--ignored_tservers' flag and adds a '--move_replicas_from_ignored_tservers' flag to the `kudu rebalance cluster` CLI tool. Once the flag '--ignored_tservers' is specified, and the flag '--move_replicas_from_ignored_tservers' is specified false, the given tablet servers are not considered as a part of the cluster, their health state and replicas on them are ignored by the rebalancer tool. If '--move_replicas_from_ignored_tservers' is specified true, unhealthy tservers in the given tservers will also be ignored by the rebalancer tool. But for healthy ignored tservers, replicas on them would be moved to other tservers before starting the rebalancing process, when running the rebalancing, these tservers are not considered as a part of the cluster.

[kudu-CR] [clock] add a built-in NTP client implementation
Alexey Serbin has uploaded a new patch set (#16) to the change originally created by Todd Lipcon. ( http://gerrit.cloudera.org:8080/7477 ) Change subject: [clock] add a built-in NTP client implementation .. [clock] add a built-in NTP client implementation This adds a stripped-down implementation of built-in NTP client without any reliance on the kernel NTP discipline. This initial implementation doesn't have all the necessary sanity checks for true time that RFC-compliant client would have and doesn't implement everything from RFC5905. However, this implementation is good enough for running with well behaved and properly configured reference NTP servers such as servers from pool.ntp.org, other public-domain NTP services, and properly configured NTP servers in local network. This is a first step on the road to eventually have robust and RFC-compliant Kudu's own NTP client that is able to detect and reject misbehaving and rogue reference NTP servers. For Kudu, this should hopefully make it easier for users to configure NTP even if they don't have root, and also can maintain better clock error than the system implementation, since we can prioritize low error bounds rather than low jitter. This patch doesn't have the knobs to control error vs jitter yet, though. This patch also contains tests to verify the newly introduced functionality in scenarios when the built-in NTP client is pointed to various combinations of properly configured NTP servers or unintentionally misconfigured/unavailable ones.

[kudu-CR] [clock] add a built-in NTP client implementation
Alexey Serbin has uploaded a new patch set (#15) to the change originally created by Todd Lipcon. ( http://gerrit.cloudera.org:8080/7477 ) Change subject: [clock] add a built-in NTP client implementation .. [clock] add a built-in NTP client implementation This adds a stripped-down implementation of built-in NTP client without any reliance on the kernel NTP discipline. This initial implementation doesn't have all the necessary sanity checks for true time that RFC-compliant client would have and doesn't implement everything from RFC5905. However, this implementation is good enough for running with well behaved and properly configured reference NTP servers such as servers from pool.ntp.org, other public-domain NTP services, and properly configured NTP servers in local network. This is a first step on the road to eventually have robust and RFC-compliant Kudu's own NTP client that is able to detect and reject misbehaving and rogue reference NTP servers. For Kudu, this should hopefully make it easier for users to configure NTP even if they don't have root, and also can maintain better clock error than the system implementation, since we can prioritize low error bounds rather than low jitter. This patch doesn't have the knobs to control error vs jitter yet, though. This patch also contains tests to verify the newly introduced functionality in scenarios when the built-in NTP client is pointed to various combinations of properly configured NTP servers or unintentionally misconfigured/unavailable ones.

[kudu-CR] WIP KUDU-2780: create thread for auto-rebalancing
Hello Tidy Bot, Alexey Serbin, Kudu Jenkins, I'd like you to reexamine a change. Please visit http://gerrit.cloudera.org:8080/14177 to look at the new patch set (#3). Change subject: WIP KUDU-2780: create thread for auto-rebalancing .. WIP KUDU-2780: create thread for auto-rebalancing Created auto-rebalancer thread in background tasks of catalog manager. Set up framework for auto-rebalancing loop. Loop retrieves information on tservers, tables, and tablets for rebalancing. The number of replica moves per loop iteration is controlled by a flag. If there are placement policy violations, the current loop iteration will only perform replica moves to reinstate the policy. Otherwise, the auto-rebalancer will perform moves to do inter-location(cross-location), then intra-location(by table then by tserver) rebalancing. If the cluster is balanced, the current rebalancing cycle completes, and the thread will sleep for an interval, controlled by another flag.

In addition to changes in the catalog manager and tservers, do you think we need to update the kudu CLI tooling to report on the maintenance mode of tablet servers?

Change subject: [mini_cluster] introduce 'builtin' clock source ..

With this patch, it's possible to synchronize the built-in NTP client of the minicluster's masters and tablet servers with chronyd NTP server which is run as a part of the minicluster as well. The latter runs in server-only mode, using the machine's clock as a reference.
