Re: [EXT] New to Nifi - Failed to update database due to a failed batch update
Hi Aruna,
The XML files in the Gist page are NiFi Templates.
You can import those XML from NiFi UI. Please look at this documentation
for detail:
https://nifi.apache.org/docs/nifi-docs/html/user-guide.html#Import_Template
As to PutDatabase doing nothing, the '1' on the right top corner of
PutDatabaseRecord indicates that one thread is running for this processor
currently.
That's strange if you don't see anything happening with it for 30 min, the
thread may be blocked unexpectedly.
If possible please take a thread dump with following command and share it
with us:
$NIFI_HOME/bin/nifi.sh dump
Then thread dump is logged at
$NIFI_HOME/logs/nifi-bootstrap
Also, please share PutDatabaseRecord and its record reader configurations
for further investigation.
Thanks,
Koji

Re: [EXT] New to Nifi - Failed to update database due to a failed batch update
Hi Aruna,
To explain details, I've summarized two different approaches to load a CSV
file into a Table in this Gist page:
https://gist.github.com/ijokarumawak/b37db141b4d04c2da124c1a6d922f81f
One is using ConvertCSVToAvro and few additional processors.
I didn't use ReplaceText as I thought altering raw SQL string would be
error prone.
This approach should work with older version of NiFi (I see you're using
NiFi 1.2.0 in your screenshot).
The another way is to use PutDatabaseRecord.
This is recommended if you're able to upgrade your NiFi installation.
I hope you find these examples useful.
Thanks,
Koji

Hi Aruna,
The placeholders in your ReplaceText configuration, such as '${city_name}' are
NiFi Expression Language. If the incoming FlowFile has such FlowFile
Attributes, those can be replaced with FlowFile Attribute values. But I suspect
FlowFile doesn't have those attributes since ReplaceText is connected right
after FetchS3Object.
You need to extract values from FlowFile content into FlowFile attribute
somehow, for example, if the data fetched from S3 is a JSON, use
EvaluateJsonPath before ReplaceText.
BTW, I think you don't need to use FetchS3Object because PutS3Object passes the
data object to its 'success' relationship. You can connect 'success'
relationship to downstream flow like:
PutS3Object -> EvaluateJsonPath -> ReplaceText -> PutSQL
Also if you can upgrade NiFi to 1.3.0, PutDatabaseRecord can make the flow
simpler and more efficient:
PutS3Objecct -> PutDatabaseRecord (with arbitrary RecordReader)

Koji

Hi Aruna,
The placeholders in your ReplaceText configuration, such as
'${city_name}' are NiFi Expression Language. If the incoming FlowFile
has such FlowFile Attributes, those can be replaced with FlowFile
Attribute values. But I suspect FlowFile doesn't have those attributes
since ReplaceText is connected right after FetchS3Object.
You need to extract values from FlowFile content into FlowFile
attribute somehow, for example, if the data fetched from S3 is a JSON,
use EvaluateJsonPath before ReplaceText.
BTW, I think you don't need to use FetchS3Object because PutS3Object
passes the data object to its 'success' relationship. You can connect
'success' relationship to downstream flow like:
PutS3Object -> EvaluateJsonPath -> ReplaceText -> PutSQL
Also if you can upgrade NiFi to 1.3.0, PutDatabaseRecord can make the
flow simpler and more efficient:
PutS3Objecct -> PutDatabaseRecord (with arbitrary RecordReader)
Thanks,
Koji

RE: [EXT] New to Nifi - Failed to update database due to a failed batch update
I updated the insert statement to be in a single line. Again it failed. I
checked the flow file.
INSERT INTO ADR_SUB_NIFI (enrlmt_id, city_name, zip_cd, state_cd) VALUES ('',
'', '', '')
What could be the reason for the values to be blank instead of actual values
from the CSV file?

Since you are using ReplaceText, you can view the contents of the FlowFile and
check that you can copy/paste the SQL and execute it by hand in Postgres.
If all that works try setting the batch size on PutSQL to 1 record. This will
help check if it’s all records that are having trouble, or just a few bad

Hi,
I am new to Nifi. I am trying to load a CSV file into S3 bucket and then load
into postgres database. Please see screenshots below. This is what I have done.
I am successful till “Replace Text”. But I am not sure if the replace text is
creating the insert query properly. When I start the PutSQL, it fails with this
error “Failed to update database due to a failed batch update. There were a
total of 30 FlowFiles that failed, 0 that succeeded, and 0 that were not

I tried to see if I can find something in the failure flow file but when I
click on View or Download, nothing is happening. I would really appreciate any
kind of guidance to make this work.

Use the Download button right next to View, then open it in a text editor.

RE: [EXT] New to Nifi - Failed to update database due to a failed batch update
Hi Aruna, Since you are using ReplaceText, you can view the contents of the FlowFile and check that you can copy/paste the SQL and execute it by hand in Postgres. If all that works try setting the batch size on PutSQL to 1 record. This will help check if it's all records that are having trouble, or just a few bad records. --Peter From: Aruna Sankaralingam [mailto:aruna.sankaralin...@cormac-corp.com] Sent: Saturday, September 23, 2017 2:57 AM To: users@nifi.apache.org Subject: [EXT] New to Nifi - Failed to update database due to a failed batch update Hi, I am new to Nifi.
