> Clear redundant memstore scanners
> ---------------------------------
>
> Key: HBASE-18019
> URL: https://issues.apache.org/jira/browse/HBASE-18019
> Project: HBase
> Issue Type: Improvement
> Affects Versions: 2.0.0
> Reporter: Chia-Ping Tsai
> Assignee: Chia-Ping Tsai
> Fix For: 2.0.0
>
> Attachments: HBASE-18019.v0.patch
>
>
> The HBASE-17655 remove the MemStoreScanner and it causes that the
> MemStore#getScanner(readpt) returns multi KeyValueScanner which consist of
> active, snapshot and pipeline. But StoreScanner only remove one mem scanner
> when refreshing current scanners.
> {code}
> for (int i = 0; i < currentScanners.size(); i++) {
> if (!currentScanners.get(i).isFileScanner()) {
> currentScanners.remove(i);
> break;
> }
> }
> {code}
> The older scanners kept in the StoreScanner will hinder GC from releasing
> memory and lead to multiple scans on the same data.
