ramkrishna.s.vasudevan updated HBASE-14643: ------------------------------------------- Summary: Avoid Splits from once again opening a closed reader for fetching the first and last key (was: Avoid Splits to create a closed reader for fetching the first and last key) > Avoid Splits from once again opening a closed reader for fetching the first > and last key > ---------------------------------------------------------------------------------------- > > Key: HBASE-14643 > URL: https://issues.apache.org/jira/browse/HBASE-14643 > Project: HBase > Issue Type: Improvement > Affects Versions: 2.0.0 > Reporter: ramkrishna.s.vasudevan > > Currently split flow is such that we close the parent region and all its > store file readers are also closed. After that inorder to split the > reference files we need the first and last keys for which once again open the > readers on those store files. This could be costlier operation considering > the fact that it has to contact the HDFS for this close and open operation. > This JIRA is to see if we can improve this. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
