We are looking for a short term to long term HBASE specialist. We have a Hadoop Cluster, on top of which we use HBASE. The cluster is about 200TB in size and will grow fast. We use HBASE. Hadoop, Ubuntu, Python, Thrift & RabbitMQ We are struggling to achieve insert rates to HBASE - we seem to be limited to around 2000 inserts per second, we need to be way above this. We are repeatedly hitting the following errors; 2016-08-12 13:30:42,956 INFO [thrift-worker-50] client.AsyncProcess: #45890, waiting for some tasks to finish. Expected max=0, tasksInProgress=14 2016-08-12 13:30:43,001 INFO [hconnection-0x59379549-shared--pool2-t485] client.AsyncProcess: #45903, table=TheField, attempt=14/35 failed=4ops, last exception: org.apache.hadoop.hbase.NotServingRegionException: org.apache.hadoo p.hbase.NotServingRegionException: Region AND 2016-08-12 16:42:51,422 INFO [main] util.HBaseFsck: Loading regionsinfo from the hbase:meta table ERROR: Empty REGIONINFO_QUALIFIER found in hbase:meta ERROR: Empty REGIONINFO_QUALIFIER found in hbase:meta We are seeking someone with experience of HBASE and associated technologies. If you are familiar with troubleshooting HBASE and you have a strong opinion as to why we are having these problems. Please apply. You will need to sign an NDA. We will be also supplying regular work should you be ably to help us with our issues. Thanks, Dave.
