Íñigo Goiri commented on HDFS-14710: ------------------------------------ Thanks [~xuzq_zander] for working on this. * We should create an invokeSingle method that uses the block but also does the casting (we have another invokeSingle that does it {{public <T> T invokeSingle(final String nsId, RemoteMethod method, Class<T> clazz)}}. * We need some unit tests which ideally would check the number of calls to asses the improvement. > RBF: Improve some RPC performances > ---------------------------------- > > Key: HDFS-14710 > URL: https://issues.apache.org/jira/browse/HDFS-14710 > Project: Hadoop HDFS > Issue Type: Improvement > Components: rbf > Reporter: xuzq > Assignee: xuzq > Priority: Minor > Attachments: HDFS-14710-trunk-001.patch > > > We can improve some RPC performance if the extendedBlock is not null. > Such as addBlock, getAdditionalDatanode and complete. > Since HDFS encourages user to write large files, so the extendedBlock is not > null in most case. > In the scenario of Multiple Destination and large file, the effect is more > obvious. -- This message was sent by Atlassian JIRA (v7.6.14#76016) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
