------------------------------
Summary: RBF: ConnectionPool should return first usable connection
Key: HDFS-13232
URL: https://issues.apache.org/jira/browse/HDFS-13232
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: Wei Yan
Assignee: Wei Yan
In current ConnectionPool.getConnection(), it will return the first active
connection:
{code:java}
for (int i=0; i<size; i++) {
int index = (threadIndex + i) % size;
conn = tmpConnections.get(index);
if (conn != null && !conn.isUsable()) {
return conn;
}
}
{code}
Here "!conn.isUsable()" should be "conn.isUsable()".
