Description

To repro:

$ cat sample.json
{"foo":1}

$ java -jar ~/lib/orc-tools-1.4.0-uber.jar convert -s "struct<foo:uniontype<int,string>>" -o output.orc sample.json
log4j:WARN No appenders could be found for logger (org.apache.hadoop.metrics2.lib.MutableMetricsFactory).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
Processing sample.json
Exception in thread "main" java.lang.IllegalArgumentException: Unhandled type uniontype<int,string>
	at org.apache.orc.tools.convert.JsonReader.createConverter(JsonReader.java:233)
	at org.apache.orc.tools.convert.JsonReader.<init>(JsonReader.java:260)
	at org.apache.orc.tools.convert.ConvertTool.main(ConvertTool.java:67)
	at org.apache.orc.tools.Driver.main(Driver.java:112)

Seems like JsonReader.createConverter does not support UNION.
