As per my analysis, I understand that org.apache.hive.hcatalog.data.JsonSerDe doesn't support the JSON which starts with square bracket "[".

Since it is weird behavior, I have rechecked all the memory usage and configuration and noticed that it was due to TEZ memory set to Yarn Max memory. After reducing the TEZ memory, this is fixed.

Thank you @jbarnett Yes, it worked as well to me the simple json format after correcting the schema but the other format JSON starts with Square bracket that requires a tweak to work it. Receiving hundreds of files, and 1000s of Array elements in each file as below format: [{ "id":1, "nm":"Edward the
Elder", "cty":"United Kingdom",
"hse":"House of Wessex", "yrs":"899925"
}, { "id":2, "nm":"Edward the Elder",
"cty":"United Kingdom", "hse":"House of
Wessex", "yrs":"899925" }] However, JSON SerDe only supporting single line JSON meaning each JSON
doc have to be in a different line otherwise Array of JSON objects in the below updated format: { "jsondata":[{ "id":1,
"nm":"Edward the Elder", "cty":"United
Kingdom", "hse":"House of Wessex",
"yrs":"899925" }] } And, the schema: CREATE EXTERNAL TABLE IF NOT EXISTS TestJson1 (jsondata
array<struct<id:int,nm:varchar(30),cty:varchar(30),hse:varchar(30),yrs:varchar(20)>>) ROW FORMAT SERDE 'org.apache.hive.hcatalog.data.JsonSerDe' Location '/data/3rdPartyData/Hive'; Any thoughts here to manage SerDe/Schema without updating the source files?
