Hi all,
I run elastic on YARN refer to this page:[https://www.elastic.co/guide/en/elasticsearch/hadoop/master/ey-usage.html#yarn-provision-es](https://www.elastic.co/guide/en/elasticsearch/hadoop/master/ey-usage.html#yarn-provision-es)
I saw that the elasticsearch service runs on datanode randomly, and the data of elasticsearch are stored locally, not in HDFS. How could this be?
As i see, the home page of es-hadoop show me that es-hadoop should make elasticsearhc can read and store data on hdfs, is it right ?
Could anybody please show me a examples of successful installation? better with installation documentation . i need it so much.
Thank you!

If one _really_ wants to run ES directly on HDFS they can do so right now by mounting HDFS as a local NFS partition. However it will not only be slow but also there might be some data loss due to the various semantics - HDFS is not an actual file system.
As for the data, it can be indexed and query from Hadoop (and its various libraries) in a native, parallel way through the ES-Hadoop connector.

Hi Costin,
Many thanks for your kindly tips.
Still have questions that:
1)how could you solve the problem that elasticsearch service runs on datanode randomly? it confuses me for a long time.
2)could you please show me a examples of successful installation? better with installation documentation
Best wishes.

You're welcome.
1. by taking care of provisioning by yourself. Puppet, chef, basic ssh+scripts, whatever it's easier for you to deploy ES on the given machines. YARN doesn't provide any type of provisioning and makes no guarantees of where a process (short-lived) runs.
2. see 1. If you really want to use YARN, the docs already contain examples of how to start and stop it. If you need finer grained control , etc.., then I'm afraid ES-YARN does not provide them, at least in its current form.

Hi ,
I am Facing same problem as yours. If you have done it please let me know how can i figure out this problem.
I have hadoop cluster my elasticsearch service randomly runs on datanode as yours but whenever i put data on my es it start storing it in default elasticsearch datapath.
Please help me out i am stucked in it for long time.But In case of single hadoop node and single es its works fine.
