Allen Sooredoo commented on SOLR-14993:
---------------------------------------
Hi,
sorry about that, I wanted to do a very quick fix in github and link it
here, but it turns out I need much more time to write all the tests and
submit a proper PR.
Use case:
- I add to every configset a file called id.txt which contains the id of
the configset (positive integer)
- When I want to update it (to add new synonyms for instance), I first use `
zkClient.downloadConfig(configSetName, directory)` (Solrj) to download the
configset and check the id inside the file before proceeding.
Issue:
- If the id fits on 1 byte, the file is created by its content is not
downloaded because of this check:
```
private static int copyDataDown(SolrZkClient zkClient, String zkPath, File
file) throws IOException, KeeperException, InterruptedException { byte[]
data = zkClient.getData(zkPath, null, null, true); if (data != null && data.
length > 1) { // There are apparently basically empty ZNodes. ```
Changing it to `data.length > 0` would solve my problem, however I may need
more time to test that this "empty ZNodes" issue doesn't reappear as a side
effect.
What do you think?
