-------------------------------
Summary: Erasure Coding: update invalidateBlock(..) logic for
striped block
Key: HDFS-8604
URL: https://issues.apache.org/jira/browse/HDFS-8604
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: Walter Su
Assignee: Walter Su
{code}
private boolean invalidateBlock(BlockToMarkCorrupt b, DatanodeInfo dn
) throws IOException {
..
} else if (nr.liveReplicas() >= 1) {
// If we have at least one copy on a live node, then we can delete it.
addToInvalidates(b.corrupted, dn);
removeStoredBlock(b.stored, node);
{code}
We don't delete corrupted block if all we left is corrupted block. We give user
the decision. So user has chance to recover it manually.
We should not compare liveReplicas() of Striped block with "1". The logic need
update.
