Boglarka Egyed commented on SQOOP-3389:
---------------------------------------
Hi [~devin.bost],
Java target version in Sqoop 1.4.7 is 1.7, see these lines in the build.xml
file: [https://github.com/apache/sqoop/blob/branch-1.4.7/build.xml#L118-L119,]
unfortunately the COMPILING and README text files contain misleading
information about using version 1.6. It will be bumped and corrected to 1.8 in
the very next release by the way.
Could you please try to build Sqoop 1.4.7 with Java 1.7?
Thank you,
Bogi

> When building Sqoop 1.4.7 with Java SDK 1.6.0_45 and Ant 1.7.1 on Windows in

> I experienced similar build errors on a different project, which I traced to
> this issue:
> [https://stackoverflow.com/questions/21245796/javax-net-ssl-sslhandshakeexception-remote-host-closed-connection-during-handsh/22629008]
> The problem, however, is that because this particular build of Sqoop requires
> Java 1.6, TLS v1.2 is unsupported, according to here:
> [https://stackoverflow.com/questions/33364100/how-to-use-tls-1-2-in-java-6]
> which is a problem because some public repositories have dropped support for
> TLS versions prior to 1.2, as reported here:
> [https://github.com/Microsoft/vcpkg/issues/2969]
> and here:
> [https://blog.github.com/2018-02-23-weak-cryptographic-standards-removed/]
> If it is impossible now to pull the upstream dependencies when building via
> Ant due to TLS 1.2 being unsupported in Java 1.6, then this is a critical
> dependency conflict.
> If additional configuration steps are required to be able to successfully
> build, they are not documented in any of the Sqoop documentation that I have
> found.
