@shivaram thanks for the advice.
Some Issue being faced by me
- While reading a large file from Rstudio and trying to kill the the
process using `Sys.getpid()`, I tried to interrupt the process using the
signals `pskill(pid, signal = SIGUSR1/SIGCHLD)`. This does not seem to affect
my R session and does not print `Interrupt` (As per my code below).
```
readBinFully <- function(con, what, n = 1L, size = NA_integer_, endian) {
while (n > 0) {
if (con == 0) {
cat("Interrupt")
}
readBin(con, what, n, size, endian = "big")
}
}
```
- `sparkr.zip` obtained after running `install-dev.sh` does not seem to
reflect the changes made in my R session. (Restarting R studio solves this
problem). Code below
```
rm(list=ls())
Sys.setenv(SPARK_HOME="/Users/krishna/Experiment/spark")
.libPaths(c(file.path(Sys.getenv("SPARK_HOME"), "R", "lib"), .libPaths()))
library(SparkR)
```
- To check if there are more bytes to read, I have tried the code below.
Which fails the tests in `run-tests.sh`
```
while (size > 0) {
...
}
```
I see that variable size takes the value `NA`.
Please advice on how I should be approaching these issues.
Thanks
