Jian He commented on YARN-3672:
-------------------------------
- How will the RM failover play together with YARN-3673 ? Let’s say
subCluster1(RM1, RM2), subCluster2(RM3, RM4). Looks like the implementation
will ignore cluster intra-failover and do cluster inter-failover only ?
- question for such API. It asks for a specific subCluster info, do we still
need the filterInactiveSubClusters flag ? Even if it’s required, the behavior
for the if/else is inconsistent, the if case is honoring the flag, while the
else doesn’t.
{code}
public SubClusterInfo getSubCluster(final SubClusterId subClusterId,
final boolean filterInactiveSubClusters) throws YarnException {
if (isCachingEnabled()) {
return getSubClusters(filterInactiveSubClusters).get(subClusterId);
} else {
return stateStore
.getSubCluster(GetSubClusterInfoRequest.newInstance(subClusterId))
.getSubClusterInfo();
}
}
{code}
- I think we should not reuse these two configs for retry, the default value of
both is zero.
{code}
conf.getInt(YarnConfiguration.CLIENT_FAILOVER_RETRIES,
YarnConfiguration.DEFAULT_CLIENT_FAILOVER_RETRIES),
conf.getLong(
YarnConfiguration.CLIENT_FAILOVER_RETRIES_ON_SOCKET_TIMEOUTS,
YarnConfiguration.DEFAULT_CLIENT_FAILOVER_RETRIES_ON_SOCKET_TIMEOUTS),
{code}
