Dave Marion commented on ACCUMULO-2222: --------------------------------------- This may not be true depending on the configuration. https://issues.apache.org/jira/browse/HDFS-3702 > add footnote to documentation regarding rfile placement in HDFS in relation > to tserver assignment > ------------------------------------------------------------------------------------------------- > > Key: ACCUMULO-2222 > URL: https://issues.apache.org/jira/browse/ACCUMULO-2222 > Project: Accumulo > Issue Type: Improvement > Components: docs > Reporter: Arshak Navruzyan > > suggest adding a footnote to "2.3.1. Tablet Server." Perhaps something like > this: > HDFS's block placement policy determines which data nodes will hold a replica > of the Accumulo RFile. The default HDFS placement policy is to put one > replica on one node in the local rack, another on a node in a different > (remote) rack, and the last on a different node in the same remote rack. > (http://hadoop.apache.org/docs/stable1/hdfs_design.html) > This generally ensures that the server assigned to a particular tablet will > be a HDFS replication location for the tablet's underlying RFile. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
