Storing and processing timeseries with Hadoop
<p>I would like to store a large amount of timeseries from devices. Also these timeseries have to be validated, can be modified by an operator and have to be exported to other systems. Holes in the timeseries must be found. Timeseries must be shown in the UI filtered by serialnumber and date range.</p>

<p>We have thought about using hadoop, hbase, opentsdb and spark for this scenario.</p>

<p>What do you think about it? Can Spark connect to opentsdb easily?</p>

<p>Thanks</p>
