### What changes were proposed in this pull request? This issue fixes an issue that indentation of multiple output JSON records in a single split file are broken except for the first record in the split when `pretty` option is `true`. ``` // Run in the Spark Shell. // Set spark.sql.leafNodeDefaultParallelism to 1 for the current master. // Or set spark.default.parallelism for the previous releases. spark.conf.set("spark.sql.leafNodeDefaultParallelism", 1) val df = Seq("a", "b", "c").toDF df.write.option("pretty", "true").json("/path/to/output") # Run in a Shell $ cat /path/to/output/*.json { "value" : "a" } { "value" : "b" } { "value" : "c" } ``` ### Why are the changes needed? It's not pretty even though `pretty` option is true. ### Does this PR introduce _any_ user-facing change? I think "No". Indentation style is changed but JSON format is not changed. ### How was this patch tested? New test. Closes #32203 from sarutak/fix-ugly-indentation.
