Hi, We recently upgraded our production HDP cluster from 2.2 to 2.3.2. Phoenix was upgraded from 4.2 to 4.4. The bulk load script using psql.py which was working in Phoenix 4.2 stopped working in Phoenix 4.4. Upon investigation, I found that psql.py was failing to upsert null value into a date column which was working fine in Phoenix 4.2. It throws following error. The .csv file has an empty string for a date column. To rule out any upgrade issue, I created a temp table in Phoenix 4.4 and tried to insert a record using psql.py but it failed giving below error for null date value.
*java.lang.IllegalArgumentException: Invalid format: ""* create table temp1 (pk varchar, c1 varchar, c2 date, c3 integer, c4 varchar constraint pk_temp1 primary key (pk)) Values used in .csv file: I ran psql.py separately with two different records. p1~abc~~1~x (this one gives error) p2~abc~2015-11-24 00:00:00~1~x (this one is getting inserted fine) Bulk load command: /usr/hdp/current/phoenix-client/bin/psql.py -t TEMP1 -d '~' -s <my host>:2181:/hbase-unsecure temp1_insert.csv For column other than date type, psql.py can upsert null value. Has anyone experienced this issue? Do I need to set any property in hbase-site.xml to allow null value in date column?
