> DFSClient support lazy resolve host->ip.
> ----------------------------------------
>
> Key: HDFS-17333
> URL: https://issues.apache.org/jira/browse/HDFS-17333
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Jian Zhang
> Assignee: Jian Zhang
> Priority: Major
> Labels: pull-request-available
> Attachments: HDFS-17333.001.patch
>
>
> Currently, when dfsclient is started, it will resolve all hosts of all
> namservices:
> at DFSUtilClient#getAddresses(conf, null, addressKey)
> at AbstractNNFailoverProxyProvider#getProxyAddresses(URI uri,
> String addressKey)
> If the current environment where the dfsClient is located causes resolution
> of host->ip to be very slow, the existing logic will undoubtedly take a long
> time when there are too many nameservices.
> Now, each dfsclient only needs the IPs of all namenodes of a certain
> nameservice at most. A better situation is that if the namenode selected by
> dfsclient for the first time can provide the required services normally, then
> the client only needs to know the IP of this namenode. Therefore, it is not
> necessary to resolve all namenodes of all nameservices in the configuration
> file, when dfsclient is started.
> This patch supports lazy resolution of host->ip, which will only be resolved
> when the host needs to be accessed.
