hi:
I received an error. When es imported the data, it reported an error and exited, and the cluster stuck.
Elasticsearch runs on kubernetes, using the glusterfs store.
Cluster information:
sh-4.2$ curl 127.0.0.1:9200
{
"name" : "elastic-header-1",
"cluster_name" : "es-cluster",
"cluster_uuid" : "53kTWYq7RXuyyqHojyScSQ",
"version" : {
"number" : "6.4.2",
"build_flavor" : "default",
"build_type" : "tar",
"build_hash" : "04711c2",
"build_date" : "2018-09-26T13:34:09.098244Z",
"build_snapshot" : false,
"lucene_version" : "7.4.0",
"minimum_wire_compatibility_version" : "5.6.0",
"minimum_index_compatibility_version" : "5.0.0"
},
"tagline" : "You Know, for Search"
}
log:
