h2o previous version install error, saying h2o.jar download failed

I have models that depend on version 3.10.0.6 of the R package h2o. In a new machine I tried to install from the source file h2o_3.10.0.6.tar.gz,

install.packages("h2o_3.10.0.6.tar.gz", repos=NULL, type="source")

After 10 min, it came back with this complaint,

Performing one-time download of h2o.jar from
 http://s3.amazonaws.com/h2o-release/h2o/rel-turing/6/Rjar/h2o.jar 
(This could take a few minutes, please be patient...)
Warning in download.file(url = h2o_url, destfile = temp_file, mode = "wb",  :
  downloaded length 60135652 != reported length 62422402
Warning in download.file(url = h2o_url, destfile = temp_file, mode = "wb",  :
  URL 'http://s3.amazonaws.com/h2o-release/h2o/rel-turing/6/Rjar/h2o.jar': status was 'Failure when receiving data from the peer'
Error in download.file(url = h2o_url, destfile = temp_file, mode = "wb",  : 
  download from 'http://s3.amazonaws.com/h2o-release/h2o/rel-turing/6/Rjar/h2o.jar' failed

I understand it's an older version and so JVM might have been removed. But could the h2o folks leave the old JVM somewhere so folks like me could still use a previous version.

I can't replicate your error. I just downloaded the h2o_3.10.0.6.tar.gz file from the CRAN archive, and was able to install it properly, so it seems like it must be an internet connectivity issue on your end. Just did this now:

> install.packages("h2o_3.10.0.6.tar.gz", repos=NULL, type="source")
* installing *source* package ‘h2o’ ...
** package ‘h2o’ successfully unpacked and MD5 sums checked
** R
** demo
** inst
** preparing package for lazy loading
Performing one-time download of h2o.jar from
     http://s3.amazonaws.com/h2o-release/h2o/rel-turing/6/Rjar/h2o.jar
(This could take a few minutes, please be patient...)
** help
*** installing help indices
** building package indices
** testing if installed package can be loaded
* DONE (h2o)

There are a few other ways to re-install an old version of the h2o R package. If it is a CRAN release version, you can use the versions package to install any old version of a CRAN package:

install.packages("versions")
install.versions("h2o", versions = "3.10.0.6")

Any stable release of H2O can be downloaded from it's release page. The 3.10.0.6 release page is here, and if you click on the "Install in R" tab, it will show you the commands to install that version of H2O from R: 

install.packages("h2o", type="source", repos=(c("https://h2o-release.s3.amazonaws.com/h2o/rel-turing/6/R")))
