> HBASE-27659 added the `getTargetDirForTable(TableName table)` method to `IncrementalTableBackupClient`. In that method, the following line causes an URISyntaxException for a table that has a (non-default) namespace:
> {code:java}
> path = new Path(path, table.getNameAsString());{code}
> Since that resolves to "namespace:tablename". Which in turn gets parsed as a URI schema incorrectly. The resulting error:
> {code:java}
> [2025-06-25T11:16:33.844Z] Caused by: java.lang.IllegalArgumentException: java.net.URISyntaxException: Relative path in absolute URI: ngdata:CUSTOMER[2025-06-25T11:16:33.844Z]      at org.apache.hadoop.fs.Path.initialize(Path.java:264)[2025-06-25T11:16:33.844Z]      at org.apache.hadoop.fs.Path.<init>(Path.java:222)[2025-06-25T11:16:33.844Z]      at org.apache.hadoop.fs.Path.<init>(Path.java:130)[2025-06-25T11:16:33.844Z]      at org.apache.hadoop.hbase.backup.impl.IncrementalTableBackupClient.getTargetDirForTable(IncrementalTableBackupClient.java:462) {code}
> This breaks incremental backups.
