The reason I found is 
org.apache.orc.impl.TreeReaderFactory$StringDirectTreeReader's 
private final LongColumnVector scratchlcv is defined with the default length 1024, but before reading data, scratchlcv.ensureSize is missing.

ps:
create table test_orc_array(names array<string>) stored as orc;
select names from test_orc_array group by names limit 10;
