Mark Miller created SOLR-7438:
---------------------------------
Summary: Look into using new HDFS truncate feature in
HdfsTransactionLog.
Key: SOLR-7438
URL: https://issues.apache.org/jira/browse/SOLR-7438
Project: Solr
Issue Type: Improvement
Reporter: Mark Miller
Assignee: Mark Miller
Looks like truncate is added in 2.7.
See HdfsTransactionLog:
{code}
// HACK
// while waiting for HDFS-3107, instead of quickly
// dropping, we slowly apply
// This is somewhat brittle, but current usage
// allows for it
@Override
public boolean dropBufferedUpdates() {
Future<RecoveryInfo> future = applyBufferedUpdates();
if (future != null) {
try {
future.get();
} catch (InterruptedException | ExecutionException e) {
throw new RuntimeException(e);
}
}
return true;
}
{code}
