usage: org.apache.nifi.toolkit.encryptconfig.EncryptConfigMain [-h] [options]

This tool enables easy encryption and decryption of configuration files for NiFi and its sub-projects. Unprotected files can be input to this tool to be
protected by a key in a manner that is understood by NiFi. Protected files, along with a key, can be input to this tool to be unprotected, for troubleshooting
or automation purposes.

-h,--help Show usage information (this message)
--nifiRegistry Specifies to target NiFi Registry. When this flag is not included, NiFi is the target.

When targeting NiFi:
-h,--help Show usage information (this message)
-v,--verbose Sets verbose mode (default false)
-n,--niFiProperties <file> The nifi.properties file containing unprotected config values (will be overwritten unless -o is specified)
-o,--outputNiFiProperties <file> The destination nifi.properties file containing protected config values (will not modify input nifi.properties)
-l,--loginIdentityProviders <file> The login-identity-providers.xml file containing unprotected config values (will be overwritten unless -i is
specified)
-i,--outputLoginIdentityProviders <file> The destination login-identity-providers.xml file containing protected config values (will not modify input
login-identity-providers.xml)
-a,--authorizers <file> The authorizers.xml file containing unprotected config values (will be overwritten unless -u is specified)
-u,--outputAuthorizers <file> The destination authorizers.xml file containing protected config values (will not modify input authorizers.xml)
-f,--flowXml <file> The flow.xml.gz file currently protected with old password (will be overwritten unless -g is specified)
-g,--outputFlowXml <file> The destination flow.xml.gz file containing protected config values (will not modify input flow.xml.gz)
-b,--bootstrapConf <file> The bootstrap.conf file to persist master key
-k,--key <keyhex> The raw hexadecimal key to use to encrypt the sensitive properties
-e,--oldKey <keyhex> The old raw hexadecimal key to use during key migration
-p,--password <password> The password from which to derive the key to use to encrypt the sensitive properties
-w,--oldPassword <password> The old password from which to derive the key during migration
-r,--useRawKey If provided, the secure console will prompt for the raw key value in hexadecimal form
-m,--migrate If provided, the nifi.properties and/or login-identity-providers.xml sensitive properties will be re-encrypted with
a new key
-x,--encryptFlowXmlOnly If provided, the properties in flow.xml.gz will be re-encrypted with a new key but the nifi.properties and/or
login-identity-providers.xml files will not be modified
-s,--propsKey <password|keyhex> The password or key to use to encrypt the sensitive processor properties in flow.xml.gz
-A,--newFlowAlgorithm <algorithm> The algorithm to use to encrypt the sensitive processor properties in flow.xml.gz
-P,--newFlowProvider <algorithm> The security provider to use to encrypt the sensitive processor properties in flow.xml.gz
-c,--translateCli Translates the nifi.properties file to a format suitable for the NiFi CLI tool

When targeting NiFi Registry using the --nifiRegistry flag:
-h,--help Show usage information (this message)
-v,--verbose Sets verbose mode (default false)
-p,--password <password> Protect the files using a password-derived key. If an argument is not provided to this flag, interactive mode will
be triggered to prompt the user to enter the password.
-k,--key <keyhex> Protect the files using a raw hexadecimal key. If an argument is not provided to this flag, interactive mode will be
triggered to prompt the user to enter the key.
--oldPassword <password> If the input files are already protected using a password-derived key, this specifies the old password so that the
files can be unprotected before re-protecting.
--oldKey <keyhex> If the input files are already protected using a key, this specifies the raw hexadecimal key so that the files can
be unprotected before re-protecting.
-b,--bootstrapConf <file> The bootstrap.conf file containing no master key or an existing master key. If a new password or key is specified
(using -p or -k) and no output bootstrap.conf file is specified, then this file will be overwritten to persist the
new master key.
-B,--outputBootstrapConf <file> The destination bootstrap.conf file to persist master key. If specified, the input bootstrap.conf will not be
modified.
-r,--nifiRegistryProperties <file> The nifi-registry.properties file containing unprotected config values, overwritten if no output file specified.
-R,--outputNifiRegistryProperties <file> The destination nifi-registry.properties file containing protected config values.
-a,--authorizersXml <file> The authorizers.xml file containing unprotected config values, overwritten if no output file specified.
-A,--outputAuthorizersXml <file> The destination authorizers.xml file containing protected config values.
-i,--identityProvidersXml <file> The identity-providers.xml file containing unprotected config values, overwritten if no output file specified.
-I,--outputIdentityProvidersXml <file> The destination identity-providers.xml file containing protected config values.
--decrypt Can be used with -r to decrypt a previously encrypted NiFi Registry Properties file. Decrypted content is printed to
STDOUT.

@saivenkatg55 Looks like “out of memory error”. You will need to update the min and max memory settings.  They are current 128m and 256m  Try 512m and 1024m and step up increments until it will start.  

If this reply solves your issue please mark this response as the accepted solution.

[#3]

Look in the nifi-app.log and the nifi-bootstrap.log, they'll provide more information on why NiFi didn't start up. The default location of these files will be in the nifi-root-directory/logs.

[#4]

@saivenkatg55 

Your Out Of Memory (OOM) issue is occurring in the NiFi toolkit script and not in NiFi itself.  Ambari will execute the NiFi toolkit before the NiFi service itself is ever started.  If the NiFi toolkit fails, Ambari does not proceed any further.

I can see you are running HDF 3.2.0 which exposes the heap memory settings under the NiFi configs in Ambari:

Locate the above line and increase your heap settings here.  Once the toolkit script finished running which must occur before NiFi is even started, that JVM is gone.  So the memory allocation set here are short lived and will not impact available memory for your NiFi.

Hope this helps,

Matt
