@Sai Deepthi As mentioned earlier that you need to check if any string literal is not closed properly. So please check your JSON data specially around 258 character to find the issue. Unterminatedstring at 258 . Looks like the problem is somewhere neat string "lidedonde usci la farafalla ...." string which seems to be abruptly coming in your JSON file. I guess the bad characters are causing newline characters here somwhere near "riconobbe" and after "Dostoevskij" words.

IN your error we see some parsing error at character position 258. So please check the query. Caused by: org.apache.hadoop.hive.serde2.SerDeException: Row is not a valid JSON Object - JSONException: Unterminated string at 258 [character 259 line 1] at org.openx.data.jsonserde.JsonSerDe.onMalformedJson(JsonSerDe.java:412) . ...
