> ----------------------------------------------------------------
>
> Key: SOLR-7438
> URL: https://issues.apache.org/jira/browse/SOLR-7438
> Project: Solr
> Issue Type: Improvement
> Components: Hadoop Integration, hdfs
> Reporter: Mark Miller
> Assignee: Mark Miller
> Priority: Major
>
> 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}
