For example, if the NN is overloaded and a table fails to load as a result, we should log relevant HDFS client configuration option about retries/timeouts etc. > Similar improvements apply to our interaction with Sentry and the Hive Metastore. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
