With the removal of node.max_local_storage_nodes, there is no need anymore to keep the data in subfolders indexed by a node ordinal. This commit makes it so that ES 8.0 will store data directly in $DATA_DIR instead of $DATA_DIR/nodes/$nodeOrdinal. Upon startup, Elasticsearch will check to see if there is data in the old location, and automatically move it to the new location. This automatic migration only works if $nodeOrdinal is 0, i.e., multiple node instances have not previously run on the same data path, which required for node.max_local_storage_nodes to explicitly be configured. |
