У меня есть несколько эластичных индексов.Название индексов имеет определенный формат.Ниже приведены примеры моих индексов:
Теперь мне нужно переиндексировать все данные в этих индексах.Для этого я написал сценарий оболочки, который выполняет следующее:
1. Loop for all indices
1.1 create a temporary index like abc_2ab99742-94d2-43f8-a582-ce10a0f031dc_tmp.
1.2 reindix all the data from the original index to temp.
1.3 delete and re-create the original index.
1.4 reindex the data from temp to original index.
1.5 delete the temporary index.
Ниже приведен сценарий оболочки, который я написал для того же.
#!/bin/bash
ES_HOST="localhost"
ES_PORT="9200"
TMP="_tmp"
indices=$(curl -s "http://${ES_HOST}:${ES_PORT}/_cat/indices/abc_*?h=index" | egrep 'abc_[0-9a-f]{8}-([0-9a-f]{4}-){3}[0-9a-f]{8}*')
# do for all abc elastic indices
for index in $indices
do
echo "Reindex process starting for index: $index"
tmp_index=$index${TMP}
output=$(curl -X PUT "http://${ES_HOST}:${ES_PORT}/$tmp_index" -H 'Content-Type: application/json' -d'
{
"settings" : {
"index" : {
"number_of_shards" : 16,
"number_of_replicas" : 1
}
}
}')
echo "Temporary index: $tmp_index created with output: $output"
echo "Starting reindexing elastic data from original index:$index to temporary index:$tmp_index"
output=$(curl -X POST "http://${ES_HOST}:${ES_PORT}/_reindex" -H 'Content-Type: application/json' -d'
{
"source": {
"index": '"$index"'
},
"dest": {
"index": '"$tmp_index"'
}
}
')
echo "Reindexing completed from original index:$index to temporary index:$tmp_index with output: $output"
echo "Deleting $index"
output=$(curl -X DELETE "http://${ES_HOST}:${ES_PORT}/$index")
echo "$index deleted with status: $output"
echo "Creating index: $index"
output=$(curl -X PUT "http://${ES_HOST}:${ES_PORT}/$index" -H 'Content-Type: application/json' -d'
{
"settings" : {
"index" : {
"number_of_shards" : 16,
"number_of_replicas" : 1
}
}
}')
echo "Index: $index creation status: $output"
echo "Starting reindexing elastic data from temporary index:$tmp_index to original index:$index"
output=$(curl -X POST "http://${ES_HOST}:${ES_PORT}/_reindex" -H 'Content-Type: application/json' -d'
{
"source": {
"index": '"$tmp_index"'
},
"dest": {
"index": '"$index"'
}
}
')
echo "Reindexing completed from temporary index:$tmp_index to original index:$index with output: $output"
echo "Deleting $tmp_index"
output=$(curl -X DELETE "http://${ES_HOST}:${ES_PORT}/$tmp_index")
echo "$tmp_index deleted with status: $output"
done
Но яполучить исключение в команде переиндексации.Вот исключение
Reindexing completed from original index:abc_58b888be-a90f-e3be-838d-88877aee572c to temporary index:abc_58b888be-a90f-e3be-838d-88877aee572c_tmp with output: {"error":{"root_cause":[{"type":"parsing_exception","reason":"[reindex] failed to parse field [source]","line":4,"col":9}],"type":"parsing_exception","reason":"[reindex] failed to parse field [source]","line":4,"col":9,"caused_by":{"type":"json_parse_exception","reason":"Unrecognized token 'abc_58b888be': was expecting ('true', 'false' or 'null')\n at [Source: org.elasticsearch.transport.netty4.ByteBufStreamInput@39913ba; line: 4, column: 31]"}},"status":400}
Кто-нибудь может мне помочь, так как я не очень хорош в сценариях оболочки.
