CA Certificates Error when trying to connect with Impala Driver LINUX

[#1]

I followed the instructions here for setting up and configuring the Impala driver on Linux.  When I test the connection using the isql command line utility I get the following error:

[S1000][unixODBC][Cloudera][DriverSupport] (1140) Unable to load CA certificates from certs file location.  Please ensure the file exists, has read permission, and has the correct PEM format.
[ISQL]ERROR: Could not SQLConnect

My odbc.ini looks like this: 

[ODBC Data Sources]

[hadoop]
  Driver=Cloudera ODBC Driver for Impala 64-bit
  AllowHostNameCNMismatch=1
  AllowSelfSignedServerCert=1
  AuthMec=3
  CheckCertRevocation=1
  DelegateKrbCreds=0
  Host={myhost}
  KrbFQDN=_HOST
  KrbRealm={myrealm}
  KrbServiceName=impala
  Min_TLS=1.2
  Port=21050
  ServicePrincipalCanonicalization=1
  SSL=1
  TrustedCerts=/opt/cloudera/impalaodbc/lib/64/cacerts.pem
  UseKeytab=0
  UseOnlySSPI=1
  UseSASL=1
  UseSystemTrustStore=1

And the permission on /opt/cloudera/imapalaodbc/lib/64/cacerts.pem is set to 777: 

-rwxrwxrwx 1 userXXX groupXXX 246K Dec 31  2018 /opt/cloudera/impalaodbc/lib/64/cac                     erts.pem

Can anyone help resolve this error?  The cacerts.pem file has the right permission and the file certainly exists.

Oops.  Reading the docs it mentions "UseSystemTrustStore" is only valid for windows.  Removing this value from by odbc.ini fixes this issue.
