> Project: Hadoop HDFS
> Issue Type: Sub-task
> Reporter: Wei Yan
> Assignee: Ekanth S
> Priority: Minor
>
> 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()".
