Hello guys I need to create an Index by manipulating another index with java. here is my cluster specification: ES version: 6.1 source Index documents count: 1.4 billion the cluster had 2 nodes. both of them are data and master each node: 50GB RAM, CPU 10\* 2.2 GHz, SSD process average speed ( read data from the source index by scrolling + manipulating + indexing in destination index): 250k per minute. the problem is after about 1 day that was everything OK, I confront with search\_context\_missing\_exception. here is the log summary. > .. > proceed : 620910000 / 1437095913 > proceed : 620915000 / 1437095913 > proceed : 620920000 / 1437095913 > Exception in thread "main" ElasticsearchStatusException[Elasticsearch exception [type=search\_phase\_execution\_exception, reason=all shards failed]];
