Is it possibile to know where solr finished to index my data?
I work with solrcloud 4.9.0 and zookeeper for conf file manager. I have the data.import file, but in it there is only where the indexing is STARTED not when it ended.
You can get the dataimporthandler status using:
<MY_SERVER>/solr/dataimport?command=status
Reading the status you can understand if the import is still running. A similar procedure (with a different url) is advised in "Solr in Action" book in order to check if a backup is still running. Another option would involve the use of listeners as advised here.
