diqiu50 opened a new pull request, #13784:
URL: https://github.com/apache/gravitino/pull/13784
### What changes were proposed in this pull request?
`RESTUtils.encodeString` now encodes a space as `%20` instead of `+`. A
literal `+` in the input is
still encoded as `%2B`, so the result is valid as a path segment and as a
query or form value.
### Why are the changes needed?
`URLEncoder` follows form encoding and turns a space into `+`, which the
server keeps as a literal
`+` in a path segment. Objects whose names contain a space could be listed
but not loaded, for
example a JDBC table named `with space` is shown by the Trino connector but
cannot be queried.
Fix: #13781
### Does this PR introduce _any_ user-facing change?
Objects whose names contain a space can be accessed through the Java client.
### How was this patch tested?
- Updated `TestRESTUtils.testEncodeString`.
- Added `TestTableOperations.testLoadTableWithSpaceInName`, which loads a
table through the server
with a path built by `RESTUtils.encodeString`; it fails without this
change.
